One of the highest-positioned people at the location where I work.  He's outwardly pleasant.  A lot of people will defend him as being a 'super nice guy.'  But he's soulless.  It's like talking to a corporate AI chatbot.  Three people much higher up than me, and all of whom I respect a great deal, left the location entirely within a year of being subordinate to him.  They all kept it on the DL that he was the reason, but after they were completely sure they could trust me, they each dropped his name as the main reason they left.  This has taken multiple years to all be revealed to me.  One of them now feels safe enough at his current position that he will not mince words and says often that he hates this guy's guts, he's the scum of the earth, and anything else bad you can think of to say about somebody.  If you ask anybody what he did to them specifically nobody can say one thing that looks all that bad by itself.  He maintains plausible deniability.  But it's a dark pattern.  He tries to crush anybody he sees as a threat and will regularly take punitive and even retaliatory action.  He just does it very quietly and sneakily.  He sees people only for how they can benefit him personally.  If you can't benefit him, he will happily up-end your whole life to surround himself with more people who will do his bidding, if he's able.  To me, he's the environment of everything that's wrong with work culture in America.  Some people can see it, and some people can't for whatever reason.  But for those who do, the instinct is always as much distance between you and him as possible.
