If he goes it would be pretty pointless, it would be more efficient to take the village on after the war, while konoha was still rebuilding, they would have the loss of ninja which died, also they would have the burden of protecting the innocent which they won't have if he kills them already, also Taka can be matched by a number of ninja from the leaf, excluding sasuke, but it would be a wise decision to try to help naruto for the time being because if the world falls into Tobi's hands he won't get the revenge he desires, but yes if i were him i'd take taka along with me, cause even if he manages to defeat naruto he'd have to deal with a number of other ninja, in fact i think he should recruit even more ninja as Juugo and Suigetsu simply wont be enough, if suigetsu even decides to continue with sasuke
