I mean, you have to be a psychopath to amass this kind of wealth.

And being a psychopath is (usually) a defense mechanism against a trauma severe enough that being a psychopath is necessary to not go mad.

So no, psychopaths don’t feel good most of the time, they’re severely broken to the point that they’re not a fully developed personality (being a psychopath is officially called a personality disorder).

Note that a personality disorder isn’t a yes/no checkbox, but more of a spectrum. For example, being slightly histrionic is very common among actors, but it doesn’t mean they’d murder you for fun.
