Sasuke controlled the war outcome.

If he did join Madara then Naruto would've wiped the floor wit him cause Hogo would've gave Naruto everything and EMS Sasuke can't handle a JJ"S Or Rikudou lvl shinobi. That would've been his downfall joining with Madara IMO.

But...naruto couldve done the same thing.... lmao

Lol, if he joined Madara he'd also be in IT as he'd not have died (almost) and therefore no rinnegan power up.

This lol unless madara decides to stab him anyways
