Psychopathy (/saɪˈkɒpəθi/[1][2] from the Ancient Greek ψυχή "psyche", -soul, mind and πάθος, "pathos" -suffering, disease, condition[3][4]) is a personality disorder that has been variously described as characterized by shallow emotions (in particular reduced fear), stress tolerance, lacking empathy, coldheartedness, lacking guilt, egocentricity, superficial charm, manipulativeness, irresponsibility, nonplanfulness, impulsivity, and antisocial behaviors such as parasitic lifestyle and criminality. There is no consensus about the symptom criteria and there are ongoing debates regarding issues such as essential features, causes, and the possibility of treatment.[5]
