Kakashi was a good sensei

1) Sasuke left Kakashi because Orochimaru was a better teacher. Sasuke would have never reached the potential he had reached to the current manga with Kakashi by his side. If Kakashi was a better ninja and more skilled, Sasuke would have stayed and trained with him. A teacher must establish control over their classroom, with Kakashi all his students ditched his class... and went to another teacher to learn the material. That is just a sign that Kakashi really was a horrible teacher. 2) Naruto would not have mastered wind rasengan if it wasn't for Kakashi, Asuma, Jiraiya, and Yamato. You are giving Kakashi too much credit for a job that took 4 teachers to teach one student. Kakashi just told Naruto to make thousands of shadow clones and wing it that was all the training. Kakashi could not teach Naruto a technique he doesn't even know. This example would be like a English teacher needing 3 helper aids to teach ONE student one part of a subject. We do not know if Sakura worked with Kakashi and even if she did we do not see the signs that she learned anything. Sakura does not display any techniques that Kakashi knows. Jiraiya was following Orochimaru a S rank missing nin from the Hidden Leaf village all those times. Jiraiya came back when he realized Naruto was in danger. He knew that the 3rd hokage would watch over Naruto and no harm would come to him so there was no point in coming back and letting Orochimaru's actions a mystery when the safety of village could have depended on it. The 4th hokage left Jiraiya the keys to the seal in hopes that Jiraiya would train Naruto to a point where he could master the nine tail fox chakra. What abilities? When Jiraiya first met Naruto he even said he had "No talent". Naruto couldn't even mold chakra properly. So if Kakashi was such a good teacher, how come when Jiraiya first met Naruto, Naruto knew almost nothing? Jiraiya and Ebisu taught Naruto a even more complicated chakra control maintaining chakra to stand on water was a harder level than to walk on a solid surface. It took Naruto weeks to learn the Rasengan because JIRAIYA taught him a simpler form of learning it. It was not even revealed that Kakashi even knew how to do the Rasengan until arc 2. Kakashi deserves 0 credit for Naruto learning the Rasengan. It was not Naruto's fault that he was a bad student his entire life he had bad teachers. Iruka never even wanted to teach him in the first place. Naruto being this good just shows he always had talent just nobody noticed him. It is like that genius from the movie "goodwill hunting" he was a janitor at M.I.T and then some professor discovered that after days of working with him he really did have talent and was a genius. Jiraiya would count as that professor, because Jiraiya did spend a ample amount of time teaching him how to release his chakra for the summoning technique and how to control his movement of chakra and focus to learn the Rasengan, Like I said before Naruto's development as a shinobi was entirely because of Jiraiya. Kakashi did not teach Naruto a single technique that he knows today because Kakashi spent all his time teaching Sasuke. Rasenshuriken, Kakashi only taught him a way to learn it faster, but not a way to actually learn it. 3) The main lesson in learning the Chidori was for him to use it to PROTECT his friends, that was the main point of teaching him the move. Kakashi's moral lessons of friendship did not sink into Sasuke which means Kakashi failed at teaching Sasuke. 4) I stand by my original point that none of Kakashi's students passed the Chunin exams. Gaara should never have become a chunin, his mental status at that point was not fit to be a chunin. Naruto beat Neji but the majority of the judges after the fight agreed that Naruto would not have become a Chunin even after that win, because his fight style is reckless. Shikamaru became a chunin because he showed exemplary skills in strategy, calm attitude, and ability to read the opponent. Shikamaru was at the bottom of the class too at the academy, how is he an exception? If one of the students who scored the lowest at school was able to become a chunin shouldn't everybody? 5) Kakashi's original instructions were to run away when fighting Zabuza and his students still did not listen to him. Naruto and Sasuke got into the first fight even with Kakashi screaming them not to do it. This shows that Kakashi had very little faith in his students and thought they would be doomed from the start the minute he got caught No faith in students= BAD SENSEI Sasuke created Hawk and killed Karin at his convenience when she got in his way... -__- Sasuke does not care about his team at his convenience he will get rid of each one by his own hand if he needs to. "Naruto fights alone" alone meaning by himself meaning still no teamwork involved. It should not matter how powerful a shinobi is the most important part of being a shinobi is teamwork. Naruto does everything alone and he has failed to follow that rule. Again main point all of Naruto's techniques Rasengan, sage mode, shadow clone jutsu, even his taijutsu skills were not taught to him by Kakashi. Kakashi ignored Naruto's training the entire first arc after Zabuza to teach Sasuke. Rasenshuriken took the knowledge and help of 3 jonin and a sannin to teach Naruto, giving Kakashi full credit is preposterous. Kakashi should have spent more time training Naruto, he was his old sensei's kid for god's sake... Shikamaru is working hard so that in the future he can train and look after Asuma's child out of respect for his sensei, performing the necessary duties he will not be able to do anymore. Kakashi never felt any urgency to train his former teacher's kid, the teacher who saved his life many times, taught him the meaning of teamwork, and died for the village. Kakashi failed as both a student and a teacher. Sakura's main abilities are her medical ninjutsu and her strength both techniques even Kakashi does not even know. Kakashi did not teach Sakura anything she knows today. Sasuke failed to learn the moral lessons of teamwork and friendship. All of Kakashi's students except for Sasuke did not learn any of their techniques from him. Kakashi accomplished in raising up a lone wolf in Naruto, and Sasuke a terrorist both are failures on his part as a teacher.
