'cuz they ordered itachi to destroy their clan... itachi couldn't refuse cuz if he didn't kill his entire clan, a civil war would start in konoha... uchihas were planning to overthrow konoha's government.... itachi didn't want war to start, so he murdered his entire clan to prevent war... turns out, he was a really peace-loving guy
Unknown, not yet
Sasuke didn't destroy the village because it was already destroyed by Pein. Instead he goes after Danzo *spoiler* Sasuke kills Danzo but he later starts going blind because of all the fighting...
Unknown, wait and see
Sasuke isn't dead but he is planning to destroy the leaf village with his team
No. Only To Destroy It, In Shippuden. Only. Never In The First Series. So He Only Returned To The Village, To Destroy It
kiss sakura and married her
I would hate to spoil it too much for any one but, sasuke actually doesn't return to Kahona but instead creates a team to destroy it. :)
Well yes and no but frankly he is going a bit too far. But hey where would the anime be without this motive for sasuke.
yes to destroy it.
No, he returns but its to destroy the village, and hes one of the akastu
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
no sasuke will try to destroy it because when he finds about that the hokage ordered itachi to kill his clan he wants revenge and he comes to destroy konoha and naruto is to weak to defend it because of the batttle with pain
