I have a hard time psychopaths are quite as… blunt, frankly.

He pumps a lot of money into medicine research. He gave away drugs for free to people who couldn't afford it. Neither seem particularly likely for a psychopath, and even if they are, then it's a psychopath having a net positive impact.

He is, largely, just a regular but intelligent asshole. I'm getting kinda tired of seeing "charismatic, smart, has money" == "psychopath" lately.
