@Ella i personally think that he has gone through a lot, the author just doesn't want to tell us that yet. But yeah, not all abusive people are going to be bad for forever, some of them will change for the better. From what i know of, a lot of them have had a rough childhood. But that ofc doesn't mean that we excuse and forgive his actions. It's just the way that it's pictured here, it's kinda bad but idk
