In 2016 and about, whenever the subject of Trump's narcissism would come up, there were often voices eagerly reminding us that "all presidents are narcissistic" or that narcissism in politicians / public figures was not necessarily a problematic trait.

Not many at that time we're ready to acknowledge that Trump's narcissism was of the malignant kind -- many still are not despite daily evidence -- and what that meant for America and the world.

Malignant narcissism is comprised of psychopathy (lack of conscience), manipulativeness, sadism, and paranoid tendencies or full blown paranoia, in addition to narcissism. It's the most dangerous form of psychopathology known to humankind.

Malignant narcissism (MN) is not a DSM diagnosis. It's also not a mental illness (which is acquired, time limited, and curable) but rather a character problem (defect) that is unchangeable, permanent, and incurable.

Erich Fromm who created the term malignant narcissism called it the quintessence of evil and the root of the most vicious destructiveness in humans.

All tyrants in human history appear to have been afflicted with this character defect, as are most mass killers.
