Uchiha freaking Itachi from Naruto!! Seriously this guy murdered his entire clan, including his personal family, to prevent a coup d'etat against Konoha and therefore saved the village from a potentially devastating war that would have killed millions in the long run, took the blame for this deed in order to spy on the international criminal organization known as the Akatsuki for Konoha and work for his psychotic and potentially insane ancestor who helped instigate the massacre on the Uchiha clan in the first place, and risked everything to spare his little brother, Sasuke, who was ignorant of all this and caused his beloved little brother to hate him through mental torture in order to motivate him to hate Itachi and grow stronger in order to avenge his clan and therefore redeem the Uchiha clan in the eyes of Konoha. What's more, he arranged a battle to death with his little brother, allowing Sasuke to kill him in order to gain stronger techniques with his Sharingan and implanting one of his strongest techniques to guard Sasuke from Madara. Of course, all this goes to waste when Madara revealed all this to Sasuke after Itachi died, thus causing Sasuke to go on a rampage against Konoha to avenge his brother.
Because it's a big wad of spoiler tag. There has got to be a better way to phrase this.
