I dont hate him. He is a great charachter he always manages to shake up the story. He loves Konoha only his methods to achieve his goals are somewhat more drastic then those of the previous hokage's. But this guy has some balls and isn't affraid to do what ever is neccesary to come out on top. First, second and third Hokage were trying to keep the Uchiha clan under control. Danzou just killed them off. Maybe you hate him but he is efficient.
