Terpe narcissism can be part of other more complex disorders.

I quote wiki a lot and it's not always accurate but in this case I think the last one mentioned below can apply

unprincipled narcissist - including antisocial features. A charlatan - is a fraudulent, exploitative, deceptive and unscrupulous individual.
amorous narcissist - including histrionic features. The Don Juan of our times - is erotic, exhibitionist.
compensatory narcissist - including negativistic (passive-aggressive), avoidant features.
elitist narcissist - variant of pure pattern. Corresponds to Wilhelm Reich's "phallic narcissistic" personality type.
fanatic type - including paranoid features. A severely narcissistically wounded individual, usually with major paranoid tendencies who holds onto an illusion of omnipotence.
It is not unreasonable to suppose that the major dictators of our recent history have been self obsessed paranoid fanatics.

Arthur some people who rise to power manage to do so because their acting skills are incredibly comprehensive, Hitler, Stalin, Pol Pot and many many others, it's not beyond reason to question the psychology of individuals like them, I would not be surprised if narcissism was part of their psychological make-up.

Doc, yes I agree, the vast majority of us have no clue as to the real numbers and real causes of human misery, pain and self inflicted suffering, our self inflicted problems probably dwarf anything imposed on us from outside.

You have a partially valid point Nigel, people cause more pain and suffering than the natural world at least at this point in time that might change in future decades but that is another argument.
