Y'know he was always a scumbag but now that he's brainwashing someone who wasn't bad he really is next level scumbag. He could've just told her that slightly distorted truth and left it at that.
I mean he has been like one of those rapists, that were raped themselves as a kid, from the start.
One can understand where it went wrong and why he is that way, but that doesn't make him less of a bad guy.
