didn't read jjk but kakashi might be the worst teacher in history
Actually a very good one lol
Never trained sakura but doesnt matter
Made sasuke strongest out of those who were in chunin exams in one week
Thought naruto and sasuke team work + combos
Made naruto high akatuski level and helped him to create rasenshuriken
His methods also helped Naruto to master sage mode faster
btw if u think kakashi is bad teacher, gojo isnt even a teacher😂
