Sasuke Uchiha/Relationships

The relationships of Sasuke Uchiha from Naruto.
==Family==
===Itachi Uchiha===
One the most significant bonds Sasuke's ever had was with his older brother Itachi. From childhood, Sasuke remembered Itachi as a loving and caring older brother who always poked him on the forehead as a sign of affection. Sasuke looked up to his brother and often threw tantrums when Itachi was unable to spend time with him, leading Itachi to come up with games to keep Sasuke occupied. However, Sasuke felt that he lived in Itachi's shadow as there were high expectations from Sasuke like there had been from his brother, who was deemed a perfect prodigy of the Uchiha clan. Sasuke tried to surpass Itachi by excelling in his studies and learning many of the Uchiha clan's techniques. In the events leading to the clan's massacre, the relationship between Sasuke and Itachi took a turn for the worse when Itachi withdrew from the clan in midst of being suspected of murdering his best friend. Still though, Itachi seemingly still made efforts to spend time with Sasuke and offer him advice to impress their father. Sasuke was horrified to discover that Itachi had slaughtered every member of their clan and when Itachi said he spared Sasuke for being unworthy to kill. He also told the boy to hate him so that he can get stronger and exact revenge on him, which would envelop Sasuke's mind for years. As a result, Sasuke made it his life mission to kill Itachi in order to avenge their clan, causing him to become distant and cold towards others. After a humiliating defeat at Itachi's hands and being forced to relive his parents' murders, Sasuke eventually chose to make revenge a more important priority than his friends, and this would send him down the path of a rogue ninja who was willing to use any means to achieve his goal, which had never been Itachi's intent. In their first major battle, Sasuke became strong enough to be deemed a threat to Itachi but the battle comes to a stunning end when Itachi's illness caught up with him and he died. Before dropping dead to the ground, Itachi appeared to try to take Sasuke's eyes but actually poked him on the forehead. After Sasuke learned the truth about the Uchiha Clan Downfall, an enraged Sasuke vowed to destroy Konoha in order to avenge Itachi and cried for his brother's sacrifice. After being reanimated, Itachi admitted the truth to Sasuke and said he never wanted Sasuke to walk the path he is on, but this only angered Sasuke who said he could forgive Itachi but not Konoha for what it has done to him, and it was the memories of the older brother he loved that made him unwilling to give up his hatred for the village. Knowing his words weren't enough to reach Sasuke, Itachi apologized for everything he has done to Sasuke and said he didn't want Sasuke to forgive him but he said he would love Sasuke no matter what choice he made. After this and some thinking, Sasuke accepts Itachi's actions and takes on his will to protect the village. Sasuke would continue to protect the village for the rest of his life, fulfilling Itachi's wish, and Sasuke adopted Itachi's habit of poking on the forehead, which he does with his wife and daughter.
===Parents===
Sasuke had different types of relationships with his parents; a loving and close one with his mother, and a distant one with his father. His father showed more attention to Itachi for being the perfection of a Uchiha prodigy while not going as far as to speaking to Sasuke. This caused Sasuke to feel neglected and that he was living in Itachi's shadow. His mother was always showering him with love and attention to fill in the void he felt for being ignored by his father, but his mother said to him that while his father appears stoic, he actually talks about Sasuke a lot and is proud of him. When Itachi started withdrawing from the clan, Sasuke was bale to spend time with his father and won his recognition after proving himself to be a prodigy for mastering the Fire Release at a young age. Sasuke was devastated when Itachi killed their parents and still mourned them as he got older.
===Sarada Uchiha===
Sarada is Sasuke's daughter with Sakura. As the first Uchiha born since its' downfall, Sarada represents the clan's restoration. Sasuke loves his daughter more than anything and she is the reason why he continues to live. Before he left for his mission, it is hinted that Sasuke was very attentive and loving towards his daughter, as he was seen with Sakura teaching baby Sarada how to walk. Although Sasuke left when Sarada was a toddler, he never forgets about his daughter and it turns out that his lack of contact with her during his absence was because his reputation as a powerful shinobi and being an Uchiha would earn him enemies who wouldn't hesitate to harm her if they learned she was his child. Sarada has a strong attachment to her father and she always longed to meet him. When they did meet for the first time in years, Sasuke refused to answer her questions about her parentage and his absence, which briefly strained their relationship. Sarada even expressed anger at both of her parents for keeping secrets from her and doubted her father cared about her. However, Sarada learns she was wrong and her father really does love her, and he said he loved her mother as well because Sarada is the proof of their bond. While Sasuke admits he doesn't know how to be a father, he willing to apologize for his mistakes and make up for them as long as it makes Sarada happy. Sasuke is very protective of Sarada, to the point where he is willing to risk his life for her. Sasuke also doesn't hesitate to show Sarada affection in public, especially when she's upset. Although he unintentionally made her cry during their first meeting, Sasuke actually hates seeing her sad and criticizes anyone, including Naruto, for upsetting her. Sasuke harbors deep pride for his daughter she demonstrates she is a strong ninja, especially when he learns she dreams to be Hokage. In the novel Boruto: Naruto the Movie, Sasuke refers to Sarada as his beloved daughter.
==Romance==
===Sakura Haruno===
Sakura always had a crush on Sasuke since they were small children, but Sasuke often dismissed her. Her infatuation from him was rooted from his good looks and calm, collected attitude, and after being placed on the same team, she spent more time trying to win his affections rather than practicing her ninja skills. He had a low opinion of her and called her annoying for being inconsiderate of Naruto being an orphan. However, as time passed, he started to accept her as a teammate and friend, and he was willing to put his life on the line to protect her. While experimenting the powers of the Cursed Seal of Heaven for the first time, Sasuke was enraged to see Sakura hurt and repeatedly asked her to tell him who injured her before he broke the arms of the culprit. He later told Naruto to do everything in his power to save Sakura from Gaara because he didn't want to lose someone dear to him again. Sakura was the first person Sasuke trusted with the secret of him being infected with the Cursed Seal but warned her that he wouldn't forgive her if she told anyone. Sasuke would later say that his bond with Sakura had grown to the point where they can read each other's thoughts so easily. Similar to how he started treating Naruto with contempt, Sasuke, overcome with rage for not getting stronger, began rejecting Sakura before he decided to defect from Konoha. Sakura, who suspected this would happen, ran into him at the village's gate and they talked about their times together, and went as far as to desperately confess her love to him for the first time and offering to join him as long as she can be with him. Although touched, Sasuke feigned indifference and called her annoying and knocked her out to prevent her from alerting the village but not before thanking her for everything. When they reunited three years later, Sasuke denounced any bond to Sakura and was willing to kill her twice at one occasion when she stood in his way. Although distraught, Sakura was willing to kill Sasuke to prevent a war. However, with Naruto's vow to save Sasuke no matter what, Sakura decided to put all her faith in Sasuke and Naruto in fulfilling her dream of Team 7 being together again. They were able to put their differences aside as they fought the Ten-Tails, Obito, Madara, and Kaguya and, although Sasuke was impressed by her powerful strength, he initially showed disregard in helping her. However, when she saved him after he was trapped in another dimension, he held her when she was about to collapse from exhaustion and thanked her. Before leaving to fight Naruto, Sakura tried to get Sasuke to return home by telling him that she still loves him. However, while he did seem to briefly hesitate, he ended up knocking her out with a genjutsu to stop her from getting in the middle of his fight with Naruto. He also said there was no reason for them to love each other and he believed her feelings were from a failed past. Afterwards, a redeemed Sasuke apologized to Sakura, which she accepted in tears. Before leaving to his travels around the world, Sasuke poked Sakura on her forehead, finally showing his affection as he realized that he had fallen in love with her. He then promised that he would take her with him next time, which he eventually did. Years later, they got married and it turned out to be a good one.
==Friends and Allies==
===Naruto Uzumaki===
Naruto is Sasuke's best friend, teammate, and surrogate brother. As kids, they always had a rivalry over who was the strongest, but at the same time, they sympathized with each other after realizing they were both orphans and experienced tragedy in their childhood. This is seen when Sasuke called Sakura annoying for criticizing Naruto for being an orphan. In fact, Naruto recalls a time when he and Sasuke glared at each other but then they secretly smiled at the other, and he actually wanted to be friends with Sasuke all along. At 12-years-old, they accidentally have their first kiss, an incident that still haunts them. After being put on the same team, Sasuke had a low opinion of Naruto and called him a loser, but as time passed, he grew to consider Naruto as a friend and Naruto becomes the first person Sasuke develops a bond with since his clan's massacre. When he saw Naruto getting stronger, Sasuke became jealous and started treating Naruto as an enemy before he ultimately decided to sever their friendship and defect Konoha in order to get stronger. When Naruto tried to stop him, Sasuke revealed his new desire to kill Naruto but chose to spare an unconscious Naruto after their first battle. Three years later, when they reunite, Sasuke was indifferent towards Naruto and explained he spared Naruto on a whim but he vowed to finish him off for good just to prove how much he's changed since their last battle. Due to this goal, Sasuke was willing to achieve any means to gain the power he needed to defeat Naruto. As Sasuke fell deeper into darkness, Naruto was left in a deep depression of how low Sasuke had fallen and how everyone was opting to kill him to stop him but Naruto refused to give up the possibility of redeeming Sasuke. Naruto went as far as to beg the Raikage to pardon Sasuke for his crimes against his village and be beaten rather than sell out information on Sasuke. Eventually, Naruto declares to never give up on him and he will bring him back to Konoha, which angered and surprised Sasuke. This made Sasuke more determined to kill Naruto during the war and he rejected Naruto's assertion that he understood why Sasuke was so bent on revenge against Konoha. Sasuke offered Naruto two choices: kill him and be a hero or be killed and known as a loser. Naruto rejected both and said there was a third option, which was they would both die in their final battle. Naruto said he was willing to die with Sasuke in their future battle if it meant Sasuke won't be alone. Despite this, Sasuke temporarily worked together with Naruto in defeating Obito, the Ten-Tails, Madara, and Kaguya, and only protected Naruto so that he can fight him later. To fulfill his goal of creating a new ninja system through destruction and rebirth, Sasuke fought Naruto, who was the one person who can stop him, but in the battle, rather than dying, they each lost an arm. After hearing Naruto's promise to always be there for Sasuke as a friend, Sasuke admitted he was always jealous of Naruto and finally accepted defeat, allowing them to truly reconcile. It would be a good word from Naruto that would prevent Sasuke from being imprisoned for his crimes and Sasuke comes to appreciate Naruto for teaching him the true meaning of a shinobi. In the years to come, they become true surrogate brothers and best friends but remain as rivals, though on friendly terms. As adults, they tend to crack jokes with each other and are more easily able to work together as partners in combat. Sasuke would also come to greatly respect Naruto in his abilities as a Hokage and as a shinobi and all of his hardwork to get where he is at present, telling Boruto that he should not know who Naruto is now but the Naruto who had made it all the way to become Hokage.
===Kakashi Hatake===
Sasuke was always deemed as Kakashi's favorite student, since Kakashi took a personal interest in Sasuke's desire to kill Itachi for revenge. Having first hand experience in being in darkness and knowing the damage it can cause, Kakashi sought to train Sasuke and taught him the Chidori to appease his desire for power. For a while, this helped Sasuke to calm down, almost making him give up for revenge. However, when Sasuke relapsed back into his desire and started turning on his friends, Kakashi lectured Sasuke about gaining nothing but emptiness and loneliness after achieving revenge. With his teacher's words in mind, Sasuke was torn between his desire for revenge versus the bond he feels with Naruto and Sakura, and he almost gave up revenge until he was offered the opportunity to gain power from Orochimaru. After Sasuke defected, Kakashi blamed himself for this because he felt he failed as Sasuke's teacher and agreed to help Naruto and Sakura bring him back to Konoha no matter what, even with force as he knew Sasuke was becoming stronger under Orochimaru's tutelage. After three years, once Kakashi learned that Sasuke becoming a dangerous international criminal, Kakashi felt there was little to no hope left in convincing Sasuke to return to the village. Initially, he was unwilling to agree to kill Sasuke for the purpose of keeping a war from breaking out among the nations, but after seeing Sasuke try to kill Sakura, Kakashi furiously tried to finish him off. Kakashi tried once more to convince Sasuke that there was more to life than his clan and revenge, but Sasuke rejected him and made it clear he planned to kill him along with everyone of Konoha. Kakashi opted to kill Sasuke himself rather than let Naruto or Sakura deal with that burden, but Naruto prevented this and Kakashi decided to put his faith in Naruto. In the battle against Madara and Kaguya, Kakashi and his students worked together as Team 7 for the first time in four years, although Kakashi worried Sasuke's allegiance with them was temporary. This was confirmed true when Sasuke announced his desire for a revolution. At the end, after Sasuke reconciles with Naruto and Sakura, Kakashi happily looked at his team reuniting for good. After becoming the Sixth Hokage, the first act Kakashi does is pardon Sasuke for his crimes due to his services in ending the war, an act Sasuke deeply appreciates and even apologizes to Kakashi for everything he did.
===Orochimaru===
Despite seeking power from Orochimaru to get stronger, Sasuke actually despises Orochimaru and finds his use of human experiments disgusting. Although warned Orochimaru intended to use his body for his next vessal, Sasuke said he didn't care about that as long as he gained the power he desired. After three years of training with him, Sasuke decided he grew strong enough that he no longer needed Orochimaru, and admitting he never intended for Orochimaru to take his body all along. He then attacked a sickly and weakened Orochimaru, who tried to take over his body. However, Sasuke used his Cursed Seal to overpower Orochimaru and kill him with ease. Unknown to Sasuke, Orochimaru planted part of himself inside Sasuke to watch him before being killed. As the war commenced, Sasuke revived Orochimaru to have him reanimate the previous four Hokage in order for him to learn the meaning of a shinobi and what he should do in regards to protecting or destroying Konoha. Although he still intended to take Sasuke's body and expressed no interest in the war, Orochimaru was curious by the change in Sasuke and agreed to help him because he decided it was time for Sasuke to make his own decisions rather than being manipulated by others. After Sasuke decided to go to the war and help protect the village, Orochimaru decided to accompany him and convinced the previous Team Taka members to join as well and look over the things Sasuke did to them. Orochimaru seems to have developed respect for Sasuke as a result of his decision, due to that Orochimaru expressed shock when Karin feared that Sasuke was dead after being stabbed by Madara. Years after the war, Sasuke and Orochimaru met once again when Sasuke suspecting that Shin was a test subject of Orochimaru's and threatened to harm him because Shin kidnapped his wife and tried to kill his daughter.
===Kabuto Yakushi===
Sasuke never got along with Kabuto and never thought much of him, despite appreciating Kabuto's help to him and Team 7 during the Chunin Exams. He learned of Kabuto working for Orochimaru as a subordinate after he defected from Konoha. Sasuke really finds Kabuto annoying and unworthy of his attention, such as showing no emotion when Kabuto expressed horror that Sasuke killed Orochimaru. As the war was going on, Kabuto used the Reanimation Jutsu to fight against the Allied Shinobi Forces before he was confronted by Sasuke and reanimated Itachi. He tried to kill the two brothers, who joined forces to take him down and undo the Reanimation Jutsu. Kabuto tried to mock Sasuke by reminding him of his desire for revenge against the village. After his defeat, Kabuto was redeemed and decided to make amends to Itachi by saving Sasuke from dying after he was stabbed in the chest by Madara.
===Team Hebi/Taka===
====Karin====
Karin has had a deep infatuation for Sasuke since he saved her during the Chunin Exams when they were kids. They didn't formally meet until Sasuke became Orochimaru's apprentice and Karin was working as a subordinate. She developed a sexual attraction to him based on his good looks, his calm and calculating attidute, and his powerful chakra. She made attempts to seduce him or get him to be alone with her but he showed no interest in her and rejected her. However, he found her healing abilities useful for his team and she agreed to join the team after feigning rejection. While he was emotionally distant with her and the team, Sasuke protected them after being reminded of Team 7. As he became more corrupted, Karin became alarmed how "cold and dark" his chakra was but remained attracted to him. When Sasuke was willing to sacrifice her to kill Danzo, he said she became a burden to him for getting taken as a hostage so easily. He was going to kill her before Sakura intervened Enraged of what he did to her, Karin said she was done with Sasuke. She later vented her rage at him for stabbing her but when he simply apologized, she realized she couldn't stay mad at him and forgave him. In the war, she panicked as Sasuke was dying from being stabbed by Madara, and whil under the Infinite Tsukuyomi, Karin revealed that her dream was to see Sasuke smile at her. Years later, while still have feelings for Sasuke, Karin accepts that he is happy with his family; developing a friendship with Sakura and a fondness for Sarada, whom she helped deliver.
====Suigetsu====
Suigetsu was the first test experiment Sasuke released after killing Orochimaru and enlisted his help in joining his team. Sasuke seems to pay little attention to Suigetsu's actions and finds his frequent arguing with Karin annoying. However, Sasuke demonstrates his habit of pulling off tricks with Suigetsu. As Sasuke's hatred overcame him, Sasuke discarded Suigetsu and the rest of his team, leaving them in midst of a heated battle against the Kage and not caring what happened to them. Due to not knowing what Sasuke did, Suigetsu helps Sasuke decide to revive Orochimaru so he can reanimate the previous four Hokage to determine what he should do with his life. Although terrified of getting involved in the war, Suigetsu felt pressured by Orochimaru to help Sasuke. Years later, Suigetsu would be blamed for the estrangement between Sasuke and his daughter after he erroneously concluded Karin was Sarada's real mother.
====Jugo====
Jugo is very loyal to Sasuke because Jugo's surrogate brother died trying to deliver Sasuke to Orochimaru. Because of this, Jugo considers Sasuke as his brother's reincarnation and he is willing to anything for Sasuke. Unlike Karin and Suigetsu, Jugo never questions Sasuke for his actions no matter how bad or suspicious they appear, and Jugo is willing to sacrifice himself to protect Sasuke. Due to Jugo's fear of losing control of his Cursed Seal and going on a murderous rampage, Sasuke offers to keep him under control. Even after Sasuke abandoned his team, Jugo was still loyal to him due to being oblivious to what Sasuke did and immediately joined him in the war.
===Boruto Uzumaki===
When they first met, Sasuke told Naruto that his son, Boruto, reminded him of how Naruto was like as a child but Naruto insisted Boruto was similar to Sasuke at that age but retracted that as well. Naruto said Boruto is nothing like either of them because he never worked hard as a ninja, and Sasuke said the nature of a shinobi never changes, even in regards to Boruto. He was surprised when Boruto requested to be his student but Sasuke, remembering what Naruto said, told the boy to learn the Rasengan first. Although Boruto's Rasengan was small, Sasuke was impressed and was going to accept him before Boruto ran away because he though Sasuke's statement of the Rasengan being small meant he failed. Boruto then presented a standard-sized Rasengan and although Sasuke noticed the Kote Boruto was wearing and was a little disappointed, Sasuke kept quiet and agreed to train him. Sasuke taught Boruto shurikenjutsu, but when Boruto complained it was Sarada's specialty because of her being Sasuke's daughter, Sasuke taught him that hard work makes it possible for others to learn techniques that belong to certain clans. He also tells Boruto about the hardships Naruto went through to become Hokage. He and Boruto develop a familial bond to where Boruto refers to him as "Uncle Sasuke". While he was disappointed at Boruto for cheating in the Exams, he knew lecturing the boy was pointless and instead sympathized with him for making a mistake. Even as Boruto doubted his abilities, Sasuke told him that he was strong shinobi who can one day surpass Naruto. Sasuke lent his forehead protector to Boruto as a sign he recognizes Boruto as a shinobi despite his mistakes and constantly protect him in the battle against Momoshiki and Kinshiki.
===Gaara===
Sasuke first met Gaara at the Chunin exams and right away, they expressed an interest in fighting each other after noticing their respective powers. However, Sasuke was almost overpowered by Gaara's sand powers and was left severally wounded as he tried protecting Sakura and aiding Naruto. His defeat at Gaara's hands and witnessing Naruto defeat Gaara would be among Sasuke's reasons for defecting Konoha. As Gaara redeemed himself and became Kazekage, Sasuke fell deep into darkness and became an international criminal. When Sasuke attacked the Kage Summit to kill Danzo, Gaara stopped the Raikage from killing Sasuke and offered to talk to him. Gaara tried to convince Sasuke to let go of his hatred because it will gain him nothing based on his own experience of being consumed with rage and revenge, and asked him to give it up for Naruto's sake if he isn't able to see the light in darkness. Sasuke refused by saying his goals exist only in darkness and he lashed out at Gaara for saying he understands the Uchiha's anguish. Seeing the failure Sasuke had become and feeling sad for Naruto's failed attempts to save his friend, Gaara shed a tear for Sasuke and Naruto before trying to stop Sasuke who escaped. Gaara saw no hope of saving Sasuke and tried to get Naruto to give up on him, but the latter refused. Gaara then decided to put his faith in Naruto in dealing with Sasuke. After the war ended, a redeemed Sasuke seems to be on civil terms with Gaara due to that they had no problem working together in rescuing Naruto and posed for a photograph with Naruto, Boruto, and the other Kages.
===Konoha Villagers===
After the massacre of the Uchiha Clan, Sasuke was raised as an outcast and orphan just like Naruto. The Villagers and almost all of the boys from his classroom despises of him for his attitude and actions. He had attention from most of the girls except Hinata (which annoyed him). After he defected Konoha and became a missing-nin, the villagers holds an even more hatred toward than before. After his brother's death from the hemoptysis, the villagers speak ill of Itachi which caused Sasuke to attempt to kill them but stopped by "Madara". After Danzo's death and interrupt the Kage Summit, he became a threat toward not only Konoha, but other villages as well. After the Fourth Shinobi War and his last fight against Naruto, Sasuke is freed from his hatred and imprisoned by Ibiki Morino until Kakashi Hatake, Sasuke's former mentor and the Sixth Hokage, freed him for freeing everyone from the God Tree. The Villagers no longer hates Sasuke and deemed him as a threat anymore.
===Konoha Comrades===
Sasuke never had friends among his peers and considered himself far superior than his classmates until he was partnered with Naruto and Sakura. Sasuke had the attention of most of the girls (which annoyed him) but almost all of the boys disliked Sasuke for his attitude. Before defecting, Sasuke was willing to work together with his classmates but merely temporary comrades. After becoming a rogue ninja, his classmates joined together with Naruto to find him and bring him back to Sasuke, which was unsuccessful. When Naruto confronted Sasuke and shouted out that their friends risked their lives to find him, Sasuke was indifferent and retorted he didn't ask for them to look for him. Naruto further asked him if he was willing to turn his back on all of them for the sake of getting stronger and was enraged when Sasuke simply said yes. Three years later, when they learned Sasuke was an international criminal and his actions would lead to a war among the nations, they all opted to kill him to prevent this, although Naruto refused to go along with this and convinced them to let him deal with Sasuke on his own. When sasuke arrived on the battlefield, everyone was shocked and angry at him for suddenly showing up, and voiced their distrust in him but Sasuke said he didn't care what they thought of him. The fact he was willing to help them allowed them to put their ill feelings for him aside for the time being. 
==Neutral==
===Tobi/Obito Uchiha===
Tobi/Obito always had a special interest in Sasuke and intended to gain Sasuke's loyalty in order to have him destroy the village and aid the Akatsuki in the war. He was kept away from Sasuke due to Itachi secretly protecting his brother and began watching Sasuke while he fought against Itachi. After Itachi's death, Tobi/Obito approached Sasuke and told him the truth about the Uchiha Clan Downfall and Itachi's actions in order to gain Sasuke's trust. At first, Sasuke refused to believe it all and insisted that his brother was a traitor and a murderer but after remembering Itachi as a loving brother, Sasuke started to believe him and vowed vengeance against konoha. Tobi/Obito convinced Sasuke and Team Taka to join the Akatsuki but Sasuke and his group quickly defected and Tobi/Obito used Sasuke's hatred by ordering him to kill Danzo for ordering the Uchiha clan massacre and, by attacking the Kage Summit, declaring war on the five nations. Tobi/Obito reveals he has no consideration for Sasuke's well-being and will only protect him whenever it is convenient for his needs, such as when he sent a White Zetsu to inform the Kage of Sasuke's arrival despite telling Sasuke and his team to enter the Summit in secret, and when he informed Naruto of Sasuke's actions which would led to a confrontation between the two former friends. While Sasuke didn't trust Tobi/Obito, his desire to defeat Naruto was enough for a reason for Sasuke to work together with him. Ultimately, Sasuke decides to join forces with the Allied Forces and fight against Tobi/Obito, an action that didn't surprise the latter. Even after Tobi reforms back to Obito and offers to help defeat Madara and Kaguya, Sasuke was reluctant and showed no concern for Obito's well-being, but did thank him for helping Sakura save him from being trapped in another dimension. In his last act, Obito sacrifices himself to save Sasuke and Naruto from Kaguya.
==Enemies==
===Danzo Shimura===
After learning the truth about the Uchiha Clan Downfall and it was Danzo who ordered it, Sasuke was overcome with rage and vowed revenge against him. His growing hatred towards the elder caused him to become ruthless and cold to the point where Sasuke was willing to kill anyone who stood in his way. Growing fearful of Sasuke's powers, Danzo fled the Kage Summit before he was intercepted by Tobi who then brought Sasuke and Karin so that Sasuke can fight him. Confronted by Sasuke, Danzo admitted the truth but insisted he ordered the massacre in the best interest of the village and Sasuke's actions were tarnishing Itachi's sacrifice. This enraged Sasuke who fought him and killed him several times before the elder came back to life each time. Eventually realizing he was no match against Sasuke, Danzo took Karin hostage but Sasuke didn't hesitate to stab them both with Chidori. Mortally wounded, Danzo committed suicide and tried to take Sasuke and Tobi with him but failed. Sasuke expressed thrill as "killing" the man responsible for ordering the massacre of his clan, and even as an adult, he seems to have no regret. Ironically, Sasuke was willing to mirror Danzo's actions by becoming the darkness in order to peace intact among the nations and eliminate any threat for peace, although Sasuke later protects the village in darkness, he does so cautiously and peacefully.
===Madara Uchiha===
As soon as he entered in the war, Sasuke made it clear he intended to kill Madara to end the war and protect Konoha. Realizing Sasuke was related to him, Madara was amazed by Sasuke's powers and tried to appeal to him to join him, but Sasuke mocked him and refused. Although reluctant to kill a member of his clan, Madara ultimately stabbed Sasuke in the chest with his own sword and left him to die. After gaining the powers of the Six Sage, Sasuke and Naruto were ready to fight Madara after he awakened the Infinite Tsukuyomi but were left shocked when Madara was betrayed and stabbed by the Black Zetsu. In the climax, Sasuke tried to finish Madara off as he was dying but was stopped as Hashirama reconciled with Madara. Sasuke seemed deeply touched by their parting ways, likely because he knows he will have to be facing Naruto and kill him.
