1) Naruto in BM can sense evil/bad....he must already have sensed if there is something bad in Sasukes's intentions...
2) Sasuke is represented or thought to be an underdog till now...maybe he is just pretending to be....and may be he is just observing what powers/abilities do Naruto have...
3) Number of casualties of good characters are increasing and maybe these will continue to increase...but I can guarantee...this show is not meant to be a sad ending type....Somebody (maybe Naruto himself) is going to revive everybody back...we just have to wait for the answer of how..
