I'd probably list those as my top 5. Itachi (the perpetrator and victim of the Hokage who Danzo served under and which admittedly Danzo was part of the strtegising force to eliminate the Uchihas) is not a hero for eliminating his family to save Konoha, he is a hero almost entirely because in spite of the order, he not only spared Sasuke but went to extreme lengths to help Konoha still remain safe by being a double agent inside Akatsuki reporting to Danzo from time to time. Sasuke isn't a simple crybaby on the matter, he's portrayed wrongly as an emo, he's instead a rage-fuelled short-sighted individual who understandably has daddy issues given how his father only appreciated Itachi. I resent the Uchihas in general, they represent extreme right-wing ethos both in how they use their powers and how they treat their siblings, children and whatever else but Itachi was certainly an enigma not just for an Uchiha but for ninja in general.
Obviously if this was real life, someone slaughtering their entire clan just to stop a civil war would be seen as unforgivable but you need to understand some things about the Hokage and hierarchy inside Konoha before you blame Itachi for what he did. Even Danzo gets wrongly blamed for the elimination of the Uchiha, it wasn't his idea he just agreed to it because his idea was actually to recruit some Uchiha to Root (not just Itachi) and to make them cause the most aggressive Uchihas to fail. I know that I am reading in between the lines and I don't deny that Danzo was ruthless but you need to comprehend his character and the pain he had in life always being overshadowed by others and misunderstood before you call him a straight up villain. Danzo always acted in Konoha's best interests, the only time he ever waivered was when asked if he wanted to go on a suicide mission and it turned out to be a bluff mindgame by the Hokage who was cruelest to the Uchiha and that is how the next one ended up becoming Hokage. Danzo was toyed with, overlooked and underappreciated much like Sasuke was but unlike Sasuke he never betrayed Konoha or ditched his buddies.
