but merely for their own egos and hedonistic joy of despoiling the efforts of our ancestor

This is true

Even the stuff about ancestors, rich psychopaths are enraged at the idea of someone simultaneously smarter, taller and more fit than them. Somewhere, they've already come to the conclusion that they extract but do not provide value, like parasites, and the conclusion leads to solipsism and/or subvert antisocial behaviours.

In general, the rest of us have an underlying goal of coming to power and removing these people whilst changing very little, since this is all we really have wider consensus about; psychopaths are no logner necessary to the human genepool.
