In 1964, well-known psychoanalyst Erich Fromm first coined the term “malignant narcissism”. He described it as a “severe mental sickness” which embodied “the quintessence of evil”. Other clinicians agreed. Psychoanalyst Otto Kernberg defined malignant narcissism as “an extreme form of antisocial personality disorder that is manifested in a person who is pathologically grandiose, lacking in conscience and behavioural regulation, and with characteristic demonstrations of joyful cruelty and sadism.”
