i think that when sasuke looked at the village he didn't feell the hatred but pity for it..
as soon as sasuke talks with hokages...i think he'll change his mind and will go and help narut
after fighting together with itachi against kabuto sasuke's crazy mind has calmed a little bit...
seeing naruto and his friends fighting and injuring or dying will make sasuke get back to his old self..
the one who didn't wanted to see he's loved ones and comrades die...
so he'll help naruto
i'm already waiting for team 7 to fight together against enemy
they may even get new generation of sannins name
