who cares about itachy ... he's dead ,end of story,i never liked him in the 1rst place,i mean ,whatever the reason is,killing a whole clan is wrong ! ... even children... that's just wrong! no matter how you look at it.
And sasuke even said to madara,that if he thinks he's a kid rules by his emotions,then so be it.
I hope he does attack konoha and kill'em all.
Go sasuke. :)
