People tend to classify not being primarily driven by emotion as a disorder of one kind or another. Personally, I think being overly emotional is a major contributing factor to many societal issues. The cold, rational brain of a so called psychopath is more useful than that of the emotionally driven rube who can’t think of things in terms other than how it makes them feel. Losing empathy is a problem but the rest is a net benefit imo. I don’t think much, if any, emotion is required for empathy though.
