They used to be in it for the power and not the money. They were, decades ago, very low key about their finances. Nowadays they're in it for both power and money. I can't believe how much they've changed from years ago.
I think they engage in double-think were they know and pretend not to know what they're doing. They BS and then fool themselves with their BS. No reason to give them the benefit of a doubt, they're as evil as any other dictator whatever it is that they believe.
