I see, do you extend your sympathies to political terrorists who share that ideology too?
Oh, so committing heinous crimes is bad unless you have an agenda. I overuse this argument but then what makes Danzo different from someone like Hitler who had "good" intentions for his country but is a very evil man. Give as many long winded ends justify the means replies as you want. That mentality always results in bloodshed and tyranny. It's because of Danzo's methods that Pain, Kabuto and Sasuke are enemies of the konoha in the first place. You can't toy with people's lives and then be called a hero, you can call Danzo a hero all you want but when you wind up on the short end of of someone else's utilitarian stick you'll think different.
A ninja is basically a trained assassin, and a ninja village leader (Hokage) is a leader of those trained assassins, he should share that ideology, and Danzo do not kill people out of his heart's desire,he only kills when he sees a necessary threat to his village, he crushes that threat immediately, and that's what he has shown in those 2 column's, this should be the ideology of a ninja leader, if you do not know who ninja were go read a little about them.
And you are comparing Danzo to Hitler, that guy was a resist and a fool who only killed for fun and hate and, have you seen Danzo hating on someone he killed, no, he is far above That scumbag Hitler.
Where Danzo has committed a heinous crime? Killing uchiha was necessary, helping Hanzo was the right call (Akatsuki were rebels in ame but Hanzo was the official leader of the village), trying to confine Naruto was the right choice (Look what A did to Bee), trying to eliminate Sasuke was the right Call (he is a defector),killing that messenger frog was right at the moment (Naruto was not powerful enough to defeat pain),thinking of Anko's elimination was the right choice(because of her Kabuto has become this powerful), eliminate both Kabuto and Nono (this is a basic rule of secret service, when an agent becomes more of a liability,it is good to dispatch him before he become's a threat).
