I don't think that will happen cz guys like Gaara, Neji and Nagato were bad from the beginning or like they were forced to be like that from the very beginning and they never had friends where else Nagato turned out like that because of his friends death. But Sasuke though he had the reasons to be like those guys he was able to make friends but then he changed so changing from good to bad after he was sorta matured he has taken the side of evil. But even then he had some good side left in him but when he tried to sacrifice Karin that was the moment he turned into a completely evil guy I don't think he will turn out to be a good guy again.
