Eh, I dunno about that last point. "Evil" is a pretty OP strategy if you have the stomach for it, usually leaves lots of room to survive doing dumb shit. And hot DAMN greed is good at convincing people to do dumb shit!
On the one hand, don't underestimate their cunning, I do agree with that. But on the other, I've never liked the "4D chess" assumptions some folks are so willing to make (not meaning you here), it's unwise to overestimate it, too.
