The rarest of psychopathic types is the intellectual psychopath.Karl Marx, Saul Alinsky, and Cloward-Piven come to mind. Both Marx and Alinsky displayed psychopathic traits and inspired other psychopaths to infiltrate and sometimes forcibly seize governments, followed by characteristic psychopathic inefficiency, incompetence, and corruption in the administration of the state.
Psychopath Enablers and Supporters – Family and local psychopath enablers are well-identified and can be researched on the internet. Political psychopath enablers were institutionalized by Antonio Gramsci in his concept of "Corporate Communism," wherein Marxists were to infiltrate and take over cultural institutions: academia, media, legal, courts, and political parties.
Failure – In practical terms, psychopaths always fail, and psychopathic failure creates misery for families, communities, and nations. Political psychopaths and their systems fail in the manner that the Soviet Union failed, leaving massive social and economic costs for their supporters and for their opponents.
This is exactly what one might expect from the world's most severe mental disorder. Long-running psychopathic systems such as militant Islam and Marxism typically endure periods of success alternating with failure, during which massive social and economic losses are endured by everyone, supporters and opponents alike.
