He definitely pushes my buttons, that's for sure. So yeah, learning to respond rather than react is good advice, thank you. Fortunately, I won't really be around him much going forward. I'll see if the library has that book, otherwise I may end up buying it.

One thing comes to mind. As I mentioned earlier, I'm an empath. Actually, a pretty strong one at that. I have been wondering if the reason I've never felt right around him is because he doesn't express (or perhaps even feel) emotions like a normal person. To me, he's a giant void. Kind of like how you look at a shark's eyes and you see it has no soul. He's just an empty, vacuous husk of a man. Like you said, he has no moral compass and doesn't care who he destroys to get his way. It's all very Machiavellian.
