This query is counterproductively reductive. Every human alive, even the worst of them, has done at least one good thing. Many even do their bad things because they were misled to believe they were doing an overall good.
The point should be that it doesn't matter what good they've done, because the state of being a billionaire necessarily requires one to have done more net bad to the world than good. You could save a million lives by your own hand, but if you're a billionaire, it is a given that you have destroyed far more lives than that. No billionaire's heart was ever weighed by Anubis and judged worthy of the Field of Reeds.
All of them, without exception, end up as greasy streaks on the gleaming teeth of Ammit.
