A trait found in all humans at one time or another, on a spectrum of course. Many of us grow out of it to a large degree. A great and necessary survival characteristic in certain times. Not so good for personal relationships though. Not all psychopaths are criminals.

Bad is a value judgment that I hadn't really considered.

I don't think that encouraging people who are simply interested in exercising power over others has turned out very well.

instead of narcissistic psychopaths I would prefer stoics who find value in sacrificing themselves for public benefit.

its an old fashioned idea,

but better than the resigned attitude we have towards public corruption these days.
