Narcissists refuse to recognize or subordinate themselves to any higher power or authority. They see themselves as above the need. Besides, in their own minds, they’re always right. Reality sometimes clashes with that distorted self-perception. And that can prompt a narcissist’s rage.
Praising or affirming children for things they cannot legitimately claim credit (e.g., their looks, their intelligence, their innate talents, etc.) is the way we most often foster an unhealthy narcissism in them (because the aforementioned characteristics are nature-conferred as opposed to self-developed), an unfortunate circumstance only compounded by the fact that we rarely recognize and reinforce our children for what they can rightfully claim credit: the responsible exercise of their will. Recognizing and reinforcing these things helps engender healthy self-respect.
Narcissism becomes particularly “malignant” (i.e. malevolent, dangerous, harmful, incurable) when it goes beyond mere vanity and excessive self-focus. Malignant narcissists not only see themselves as superior to others but believe in their superiority to the degree that they view others as relatively worthless, expendable, and justifiably exploitable. This type of narcissism is a defining characteristic of psychopathy/sociopathy and is rooted in an individual’s deficient capacity for empathy.
