I doubt Sasuke is "evil" to begin with and Indra wasn't either. Indra's idea of peace just inherently conflicted with Asura as it stands with Naruto and Sasuke being their reincarnations they will invariably conflict there too. I believe the only reason Hagoromo gave Sasuke the other part of his power because he believes he can prevent or even end the Asura/Indra conflict. Since Hagoromo has been shown to not be infallible since he holds himself responsible for Indra being a jealous twat. In fact I'm sure had he shared his power back then as well the conflict would have happened regardless if only because Indra wants to assert his way of "peace through power" as the right one.

Beyond that Naruto will by virtue of character insist that Sasuke be forgiven and everything he did in the past be overlooked. He will almost certainly even go so far as to ignore everyone elses opinion on the matter.
