Everything "good" he has ever done was an investment against pitchforks that he knows he deserves.

If a billionaire cared about humanity, they'd give over the vast amount of their wealth immediately.
Doesn't mean refuse what they give away freely, just means never settle for just that, and never trust it'll be there next time.
