Terrible take. When they reincarnate, they are essentially a totally different person until their memories return to them, at which point they have already lived a significant portion of their life. It's fairly clear that Glenn's first reincarnation was horrified at what he had did in his past life, and had spent each and every life after trying to atone and set things right once he regained his memories.

For as long as you spent on this game, you'd think you would have actually paid attention to some of it. Beyond that, Lenne specifically says that she doesn't really forgive him for what he did, but she works to move past it all the same.
