I just came across this personality: The Machiavellian Personality
My ex-husband, in addition to borderline, fits much of this. Roughly 15% of borderlines are antisocial and 15% are narcissists.
It is marked by deceit and manipulation. The person has a cynical outlook on humanity. They feel that if they can get away with something, then it is okay.

Essentially amoral, they use other people as stepping stones to reach their goals. From a Machiavellian’s perspective, if we allow ourselves to be used, we probably deserve it. P. T. Barnum expressed this mindset: 'There’s a sucker born every minute.'”
What's worse is the 48 laws of power (which I discovered only today):
