I don't care about other people's feelings at all. I only keep good relations with people only if it benefits me. For example, I don't care if someone is upset with me unless continuing a relationship with them benefits me in some way. If someone is sad, I don't care at all. I'll only comfort them if I can get something from them in the future. I would care if someone DIED, but otherwise I'm completely non sympathetic towards other people's ailments and feelings.
