“The data available...—far greater than what we'd ever collect on any patient in a clinical practice—strongly suggest he suffers from malignant narcissism, a character defect that goes beyond a personality disorder and is not a diagnostic category in DSM. Malignant narcissism is comprised of psychopathy, sadism, Machiavellianism, and paranoid tendencies, in addition to narcissism. Unlike most personality disorders, malignant narcissism (a.k.a narcissistic psychopathy) is not treatable.” —Elizabeth Mika, MA, LCPC
