Played the villain role, motivated sasuke into becoming powerful and due to him he acquired the EMS, joined the akatsuki as a spy, he presumably was a spy for jiraiya, made a wise decision of killing the uchiha, protected Konoha from the shadows, placed a crow in naruto, coz he thought one day he might fight sasuke and the grow would use some sort of genjutsu which I don't actually remember, he practically wrote his own life and whatever he did seemed to always have worked out in the end he was on smart dude, I'm not an itachi fanboy... But I'll give him credit for his perception..what do u guys think, ohh yeah and if I did something wrong feel free to correct me =D
