Kakashi was a good sensei

1) The notation that there are no bad students just bad teachers is absurd. If a student does not want to learn or change, it does not matter how hard you try, you will never succeed. Every teacher has had this experience. Its not there fault the student failed. The student has to put in the effort as well. If you do not pay attention in class, do not study or do not do the homework, you really should not be blaming the teacher when you fail the class. "You can lead a horse to water, but you can't make it drink it". The same is with Sasuke. Sasuke did not want to let go of his hatred. It did not matter how hard Kakashi tried, because Sasuke just refused to listen to his advice and had his mind set on revenge. Its like trying to rehabilitate a drug addict who does not want to be helped. It just is not going to happen. 2) Naruto and Sakura did no even fully abandon Kakashi as a teacher. Kakashi trained Naruto in arc II, and Sakura was around Kakashi between the arcs, so she was probably trained by both the fifth hokage AND Kakashi. Kakashi did not know medical ninjitsu, but it is not his speciality. Just like a science teacher should not feel insulted if a student wants to learn literature from a literature teacher and not a science teacher. The science teacher has very little knowledge of literature, but could teach the student a lot about science. Naruto would have never been able to master wind release rasengan if it were not for Kakashi. Kakashi came up with a brilliant training method of using shadow clones. Jiraiya did not have any moral obligation to train and look after Naruto. Where was Jiraiya when his parents died? Where was Jiraiya when he was sad and alone at the academy? When Naruto felt bad about failing the exam? He abandoning Naruto for 12 years. Does not sound to me like Jiraiya really felt he had any moral obligation. Even if he did have some moral obligation to look after Naruto (which he failed miserably at) that does not mean he had to train him. Initially, Jiraiya did not want to train Naruto: http://www.hulu.com... Remember that Jiraiya was searching for a 'prophecy child' that would become a powerful ninja which would either save or destroy the world. Jiraiya was not looking to train anybody, but the 'prophecy child'. It was also after seeing his abilities that Jiraiya truly began to see Naruto as a potential good student, specifically when Naruto learned how to walk on water. Remember, it was Kakashi that taught Naruto chakra control, in the following episode:http://www.youtube.com... Chakra control is especially important if one wants to learn higher level jutsus such as Rasengan and Toad summoning that Jiraiya taught Naruto. Jiraiya would not have taught him this privately if he did not think he could do it. Remember that Naruto was the worst student at the Academy. To go from having difficulty doing basic techniques to learning an A rank technique must require a serious good intermediate teacher. Not only was Naruto able to master the Rasengan, but was able to do it before the forth Hokage was able to master it. (It took the forth Hokage three years, it took Naruto three weeks). This is like coming from the bottom of your class in high school, going to a community college and through a good teacher getting into MIT and surpassing the other MIT students. Even though it was Jiraiya who taught Naruto the Rasengan and toad summoning jutsu, it was Kakashi that taught Naruto how to control his chakra that would allow him to master these techniques. The same logic applies to how Sakura was able to get training from the Hokage. Sakura might have begged, but the Hokage would not have trained her if she did not think she would be a good student. It would help to show an interest to get into Harvard University, but if you do not have the grades or SAT to get in, your not going to get any no matter how much you want. Same applies to Sakura. Remember, the genin teams are distributed evenly in terms of ability, so Sakura would be an average exiting the academy (since Naurto was the worst and Sasuke was the best). Her skills must have improved immensely if she was able to get training from the Hokage. Also it was only after that Sasuke showed impressive abilities against Orochimaru that Orohimaru decided he was worthy of obtaining the curse mark. 3) Pro even states: "Kakashi gave the new terrorist Sasuke Uchiha his most powerful weapon (Chidori) which will eventually be used to attack the leaf village" This actually shows that Kakashi is a good teacher since he taught Sasuke a powerful technique that is a major source of Sasuke's strength. He might use it for evil, but he that's not a reflection on Kakashi's part. If I teach someone how to shoot a gun, and the person ended up becoming an expert shooter that used his skills to kill others, I was still effective in teaching the person how to shoot, the person just used it for bad reasons. Kakashi was effective in teaching Sasuke to be powerful, Sasuke just used his techniques for evil. It's not necessary about learning new ninjutsu but learning good fighting form, teamwork,strategy, speed, and chakra control. Jiraiya, the legendary sanin even stated himself "The most important ninja talent... is not the number of techniques one acquires. The most important thing... is a spirit that never gives up!" http://en.wikiquote.org.... Naruto trained with jiraiya for two and half years and did not learn many new techniques. Zabuza and haku saw a significant improvement in the teams strength after only a short time between their first and second fight even though the team did not learn any new techniques. Kakashi also taught Sakura how to escape genjitsu which turned out to be effective in stopping her from being put to sleep by the sand ninja. 4) It is true none of his students passed the chunin exams. However, this is because the chunnin exams were canceled after the sand village attacked. In fact there was only one person who actually became a chunin, and Shikamaru was an exception to the rule. Not even Gaara became a chunin, even though he became kazekage three years later. Again there were 153 students that entered into the Chunin exams, so the mere fact that two of Kakashi's students were able to make it to the final round (only 9 made it) for their first time and at such an early age in the chunin exams is incredible. Also, Naruto, Sakura, and Sasuke did not have any other teacher besides Kakashi during the Chunin exam, so their skills can not be attributed to somebody else. Iruka even saw that the students improved a lot since he had trained them. 5) In part I, there are many examples of team 7 working together. They made a strong team fighting Zabuza and Haku, and fighting in the forbidden forest. If you do not think these skills did not stick in part II, here are some examples of Sasuke and Sakura using teamwork. Sasuke created the team hawk that worked together to try to capture the eight tailed beast and attack the Kage meeting. As for Sakura, she and Chiyo showed strong teamwork in fighting against Sasori. It is true that Naruto usually fights alone but that's because Naruto is now in a league of his own and nobody would really be of good assistance to Naruto. He's even stronger then the legendary sanin. Those trying to help Naruto would only cause more harm since his opponents are also really strong, and he'd have to worry about those helping him being killed. If he could team up with someone of his ability, he would. 6) The dogs needed to smell kakashi's blood in order to find them. Blood can only be smelled if there are blood molecules in the air. It takes time for blood molecules to diffuse into the air. It is unsure how far the dogs were away from kakashi, however Kakashi needed to wait in order for the "blood molecules" to reach the dogs. That's why he stalle
