Shinra Tensei is the Deva Path's ability to manipulate repulsive force (斥力, sekiryoku) at the user's will to push matter or ninja techniques[1] away. Depending on the amount of force the user puts in this technique, it can easily shatter wood, bones, metal, or stone walls. By using this technique as a defensive measure, all attacks directed to the user will be deflected, no matter the size, power or mass. It can also be used to repel flames caught on the user's body...from narutopedia. now i think about it, he should also be able to pull Sasukes eyes out of their sockets and then its game over. But the point is, Sasuke has very, very, slim chance of success if any at all. he is going up against 6 opponents who can be revived and/or replaced, Nagato all the while not actually being at the scene of the battle,Sasuke would in effect be wasting his energy on reanimated corpses. Pain took down a village as formidable as konoha, all by himself, It was obvious he would have destroyed naruto too. powerful as Sasuke might be, Pain is still superior to him.
