Lily didn’t forgive Snape and Harry for their betrayal and she wasn’t planning to forgive them. That death eater freak and her freak of a son destroyed their lives like it didn’t matter and threw them into Azkaban. But in Azkaban, Lily and James realized, what they were going to do after they were released. First things first, they would no longer strive to get their eldest brat back. That freak should stay away from them before he was going to corrupt their two remaining children and cause them to turn away from them and the light side. If Lily could travel back in time, she wished that she had killed the boy at birth. He was nothing better than Pettigrew, Voldemort and his followers. It was evil and she should have gotten rid of the child, before it ruined their lives.
