Kakashi was a good sensei

1) Kakashi did everything he could to save Sasuke It is true that Sasuke did join Orochimaru, but Kakashi did everything he could. I would like to ask CON what Kakashi should have done to prevent Sasuke from joining Orochimaru. He knew that Sasuke was in trouble. He did not merely just watch Sasuke go join Orochimaru but did everything he could to stop him from joining. He spent extra time with Sasuke, not for favoritism, but to help Sasuke. He used a jutsu to suppress Sasuke's cursed mark. He told him not to use the chidori more than twice and never to use the chidori on a comrade. He tried to teach him that revenge was not the answer and to embrace the life and current friends he had. He stopped the fight between Naruto and Sasuke on the roof. He even refuses a mission, an order by the Hokage, in the Sasuke retrieval arc in order to find Sasuke and Naruto. Although he failed to stop the battle between Sasuke and Naruto and retrieve Sasuke, the very fact that he put his students first, even behind orders, shows great dedication. If the best doctor in the world cannot save a patient from a 100 mile car accident with major head, lung and chest trauma that does not make the doctor a bad doctor, because it was very unlikely for the person to live anyways. However, if the doctor did nothing to help save the patient then he/she would be a bad doctor. It's not about the outcome, because the outcome is not in all of one's control but attempting to get the desired result. The best doctor in the world cannot save every patient from cancer. The same goes with Kakashi. He might not have saved Sasuke, but Sasuke was already filled with hatred and revenge before meeting him. It is difficult to try to change people. If Kakashi did nothing about Sasuke's problem, he would have been a bad teacher. But he did not therefore the fact that Sasuke joined Orochimaru is not a bad reflection on Kakashi's part. 2) The fact that the students were able to obtain private training from the legendary Sanin shows how impressive Kakashi was as a teacher. Remember, the Sanin are considered the most powerful ninjas in Naruto. They are considered legendary, in a league of their own. The very fact that the three Sanin showed interested in these students just shows how capable a teacher Kikashi is. For example, if a professor teaches a student to the ability to get into MIT with a full scholarship and the student decides to go to MIT instead of staying at his/her university, it would be ridiculously to consider the professor to be a bad teacher, but instead MIT is just really good. It was not like Naruto, Sasuke, and Sakura decided to train with some random sensei like Gai sensei or Asuma but rather the best teachers in the Naruto Universe. As proof of this, when Naruto was told that he would have to train with Ebisu instead of Kikashi, Naruto flipped out. He would rather train with Ebisu instead of Naruto even though he specializes in training highly elite ninja. 3)Kakashi's students are considered the most powerful characters in the Naruto universe Naruto and Sasuke are the two most powerful characters in the Naruto universe. Naruto was able to defeat Pain, a task not even Jiraiya could do. Sasuke was able to defeat both Orochimaru and Danzo. Sakura was able to kill Sasori. This is impressive since Sasori was a senior member of Akatsuki, an organization filled with S-ranked ninjas and Sasori was able to defeat the third Kazekage. 4)Kakashi's students did exceptionally well in the Chunin exams. Kakashi's students only had the bare minimum requirements to enter the Chunin exams. It was actually recommended that such "inexperienced" students should not take part of the Chunin exams. Even though Kakashi recommended them to enter the Chunin exams, Iruka did not think the students were ready and tested Kakashi's students anyway to make sure they were prepared for the exam, and all of Kakashi's students passed Iruka's test. The fact that Iruka knew team 7, since he was their teacher earlier, and showed lack of confidence in Naruto, Sasuke and Sakura, yet after testing them had a change of mind, shows that after only a short amount of training with Kakashi, Team 7 improved a lot. Out of the 153 students to compete in the Chunin exams, 2 of Kakashi's students made it into the final round. The chance of a student making it to the final round is 6%. If only one of his students made it to the final round it would have been impressive, but two is incredible. Also note that most of those in the Chunin exam were a lot older then Naruto, Sasuke, and Sakura. The only other team to surpass Kakashi's team was those from the sand village, which had all three team members make it. However, the members from the sand village were quite older than team 7. Also note that even though Sakura did not make it to the final round, she did not lose her match but merely tied the match. Also, Naruto won his match in the final round, and Sasuke was doing well against Gaara in the final round before the Sand Ninjas attacked. 5)Kakashi taught Naruto, Sasuke, and Sakura many skills Kakshi taught the team teamwork in the first arc. This allowed Naruto and Sasuke to do well in fighting Zabuza and Haku. Kakashi taught the team how to control their chakra. Sakura's ability to control chakra allowed her skills to be recognized by the fifth hokage and she became her student. Kakashi helped Naruto learn Wind Release: Rasenshuriken , an attack that killed Kakuzu, an S ranked ninja. Kakashi taught Sasuke taijutsu and the chidori, a powerful technique that Sasuke would further use. 6)Kakashi was willing to risk his life to save his students Kakashi shows many instances of selflessness. He wanted Team 7 to flee from Zabuza even though he would die in the process. Kakashi stopped the fight between Sasuke and Naruto on the roof and tried to stop the fight again even though he had another mission.
