sasuke fighting madara because the kages will fail and naruto will be the crap out of the fake uchiha tobi because if he was a real uchiha he would have use Susanoo by now on naruto, so tob fake uchiha butt will die with the help of everybody in the war and then naruto will go help sasuke fight madara and they will win and sasuke will just leave, at this point its no way naruto can fight sasuke, you're only a naruto fan if you think naruto can stand a chance aganist sauske. sasuke has izanami, izanagi, a new susanoo, and ems, no way in hell naruto wins, yes sasuke is looking and learning everything he sees so he can use it, so no fight with naruto and sasuke and naurtuo ask everyone to leave sasuke alone and they do, thats how it we end, believe it
