Sasuke has come back to the light but i am almost certain sasuke is not going to return to the villiage and be redeemed. I have a theory...
Sasuke will join the battle against madara,Obito,and the Juubi. He will be fatally injured and he will tell naruto that he wants to do at least one thing right in his life for his friend and the ninja world. He tells naruto that he wants to give him his EMS eyes. Sakura transplants them and because naruto has uzumaki/senju/younger son blood and also witnessing the sacrifice and death of his best friend it will instantly turn into rinnegan. Naruto will be the closest thing to the sage of six paths and will defeat the remaining villains.i have had many people doubt this theory for pointless reasons but I believe it the best way for the manga to go. I just can't see the village redeeming sasuke. He will sacrifice his eyes for the ninja world like a true shinobi. Ironically it reflects back to obitos sacrifice but this time sasuke really is a hero.
