Yeah, I'll agree with Proteanmix on this. If someone is consistently and unrepentantly engaging in behavior that harms others I'm going to have a problem with that. Those consistent behaviors are who they are. Anyone can screw up and do something and be sorry for it, so that is not the end of the world. Someone who hurts people and doesn't care as a normal part of their life is someone who eventually is probably not going to make an exception for me. Plus respect is an important part of friendship for me and I can't respect that.
