Otherwise known as AsPD or more commonly, Sociopathy. Sociopaths, on contrary to common belief, are, in most cases, not criminals or murderers. Only severe sociopathy may result in crime. Sociopaths are people who disregard or violate rules of society, lacks guilt and empathy, and despite being impulsive, they are probably intelligent and charismatic.
One of my close friends has Antisocial Personality Disorder. She excels in Maths and psychology, though she constantly gets into hot water by her impulse. She values ratiocination and logical reasoning but do not understand how others feel.
