Actually, yes I think he does to get revenge on THEM after he kills his brother. Or at least that is what I've been told.
For the purpose of revenge...as far as the manga has shown us
sasuke says hes going to be like his brother itachi and put his self over the village since itachi thought sasuke was more important then the village sasuke said he vows to destroy the hidden leaf
yes Sasuke does return to the side of the leaf meaning he is once again a good person .But he does not return to the hidden village of the leaf.
Unfortunately not. Only Naruto in the game. Although I think he's in the leaf village background where the characters fight.
I think Naruto will not kill Sauske because Sauske was like him with few differences. Sauske and Naruto both dont have parents. However, Sauske still does have a brother, evil though. Naruto doesn't have any family. They have been rivals/friends since the begining of the series up until Sauske leaves the leaf village. Of course, Naruto is Naruto, and Naruto is unpredictable, so there is no sure answer at this moment. Even if he really wanted to in the last battle of The Broken Bond, yikes!
as i think, yes. because if he revolves against konoha, and fights naruto, narutos special powers, especially, that given by itachi, will activate and stop sauske to go against konoha.
He hasn't returned yet but he will be coming back to destroy leaf village unless Naruto stops him.
yes to destroy it.
no he will never come back ever he is a rouge ninja
Maybe. If they do infact show a third naruto.
yeah she is because she was with kakashi and he was from the leaf village
Maple Leaf Village was created in 1979.
