just like naruto had iruka,sasuke had naruto and kakashi and sakura.:shrug:
plus the entire village did not hate on sasuke like they did on naruto.
and,the guy had every girl of his age tagging after him.and everyone in the village,including his teachers and mentors regarded him high because of his uchiha bloodline:shrug:
in total,
sasuke's life was perfect.:shrug:
plus sasuke had been told by kakashi and naruto and everyone else tht revenge was nt going to get him anywhere.but still,the guy proved he was a retard,and went off fr his revenge,after all the efforts his friends made to bring him back.
