Did Sasuke ever consider that helping the Akatasuki gather all of the tailed beasts might be a terrible idea? Same with attacking Bee/the Kage Summit... these actions put Konoha in a difficult position; the Raikage can always say it was a Konoha missing-nin that Konoha refused to execute that was responsible for these attacks. But of course, Sasuke no longer cares about that! He's dead-set on going against his (obsessively) beloved older brother by killing everyone in Konoha.
I wonder if Sasuke is in some warped way trying to imitate Itachi by experiencing the same suffering and self-loathing... maybe he won't feel like a true man until he kills everyone he used to love. And like Itachi, he has one person whom he's never been able to bring himself to kill. I think, deep down, Sasuke probably wants to be judged for his crimes by Naruto, a former teammate and brother, just like Itachi wanted to be judged by Sasuke. That desire to be judged, and the ability to experience self-loathing, are basically the last shreds of Sasuke's former self underneath what he's become (I suppose the love for his brother counts, but that's even more warped). Of course, it's this concept of justice/revenge that Naruto has already forsaken, so Sasuke's probably going to have to face Naruto's style of justice and pay for his crimes via redemption (which will be more difficult than quietly dying).
