Sasuke lacks the balls to do so. Seriously. Sasuke never killed anyone until he went insane.
I'd like to see Sasuke and Minato helping Obito against Madara![]()
I'd be very annoyed. Plus it'd also just be...awkward?
Like, Naruto saying: "oh. Sasuke killed a dude. Who should totally be the final villain of this arc....oh. Okay."
