He left, he shuned away all the development about frienship and shit in the first part, he walked away the (almost) sacrifice of his compatriot ninjas, just for vengance, that is his crime, that and he's an emo.
Besides he pushed Itachi far beyond his safe fighting limit, caused Deidara to kill himself out of frustration, destroyed the last of Orochimaru's bodies, and summoned Manda inside a nuclear explosion. Yeah, all of them evil but more exciting characters than him.
And finaly, only with the "Spell to make Naruto real" could Sasuke come and amateratsue Kishi's ass.
The village doesn't own Sasuke. LOL Sasuke isd the best character in the manga. That perv oroo and that girl deidara is close to Sasuke. Why isn't Sasuke allowed to leave the damn village?? He didn't kill anyone. He left because he got mind rape by his brother and the CS was obviously influencing his actions. He could of slit Naruto throat if he wanted too. Naruto is the emo he cuts himself like in the 3 chapter.
