Andrea Kuszewski on similarity between Sociopath and Hero (X Altruist).

• Lykken claimed that the ability to feel and express Empathy was the main feature that defined psychopaths from heroes. He defines a psychopath as different from a sociopath, in the sense that psychopaths are born with a "defect" that disallows them to feel empathy, and sociopaths are a product of ill-rearing or a result of extreme negative trauma. The environmental misfortune then triggers impulsive hostility and the closing off from emotions, thus experiencing zero guilt or remorse for one’s actions. Essentially, Lykken claims one is genetic (psychopathy) and one is primarily the result of environmental experience (sociopathy), but they are both under the umbrella of Antisocial Personality Disorder. This point regarding etiology is debatable, and I won’t be getting into that here, but it is relevant to mention.
