What if that is Sasuke coming to fight out Pain when he see what Pain did. Will that be like Vegeta fighting Frieza before Goku. Sasuke could be redeemed a bit, because he is fighting for what is left in the village. Bring him back to team 7. That would bring an end to year of Sasuke, and tie it to Naruto's plot. For the record.. i think Sasuke, and team Gai would get destroyed by Pain.
