If we look at Sasuke's effective performance (just disregards anything he says, as if he was muted) he's a hero: he disposed of Orochimaru and his organization which was kidnapping people and experimenting on them, disposed of the bombing terrorist Deidara, killed the S-class criminal Itachi, killed Dazou who by that time was clearly a traitor of Konoha and thus became an S-class criminal, killed the original white Zetsu and a bunch of his clones and finally helped to end Edo-Tensei and thus saved a lot of alliance ninja lives. If someone wanted to spend time creating a funny alternative story he could alter all of the conversations involving Sasuke and make a completely different plot where Sasuke is actually sent to an undercover mission ordered by the hokage to dispose of S-class criminals. Sure there were moments when the picture says Sasuke is evil: when he attacks KillerBee and when he attacks Sakura and Kakashi, however it would be easy to invent some secret reasons why he did that, telling he never wanted to kill them, just like in the case of Itachi the author did the same. For example he attacked KillerBee and deliberately failed because he wanted to warn the ninjas about akatsuki's goal almost being reached, and so he caused the kage summit to happen.
He was a mindless rage driven madman before he met with Edo-Itachi, thus he didn't really have any doubts because that would require him of thinking, but he didn't think at all. Just look at his fights, he attacked kage level people, even a whole kage summit, without having any plan. He disposed of his team despite they kept saving his life, that's complete idiocy. The author just magically changes his mind sometimes, most recently when he met Itachi he stopped being a madman and began to think again. So now Naruto will be able to talk to him, Itachi did his job of changing Sasuke enough so that Naruto will be able to reach his mind later.
when you put it that way it does sounds very cool
, but still sasuke is better off as a rogue avenger
i think sasuke is shown doing these evil things,because that's just how he is, even way back he attacked itachi without thinking, i do admit there was madness in how he was going killing people and attacked the kage summit may be that was to show his hatred and power, but clearly saving others and doing good things will not suit him, but he does warn others to move out before he attacks like he warned the samurai
