Comment: (cont) BTW: the two conditions are NOT mutually exclusive:  "Those are separate definitions of these personality disorders. It is possible to be clinically diagnosed with both simultaneously. Cold callousness and lack of empathy for others, plus grandiose self-admiration and disdain for others equals a sociopathic narcissist who believes that she (or he)  deserves to exploit people and dispose of them when finished." reads like a "spot on" description of our current President.
