Laymen confuse “narcissistic style” with “narcissistic personality disorder.” Many politicians have a narcissistic style: narcissistic traits and behaviors that may amount to a narcissistic personality. They are vain, self-centered, haughty, bombastic, and infantile. Narcissistic Personality Disorder in general and “malignant narcissism” in particular are an entirely different ballgame. It’s like the difference between a social drinker and an alcoholic.
Narcissists (people with a full-fledged personality disorder) are positively dangerous: they are delusional, their thinking is clouded by grandiose fantasies, they are vindictive, contemptuous, aggressive, destructive, bullying, sadistic, and have no self-awareness. They are not curious and vehemently and sometimes violently reject any criticism, suggestion, or disagreement. They lack empathy and they exploit people, having objectified and abused them.
