I’m not sure that Soros and his cronies do wet work - they don’t need to. First, they only hire people that are both very good at what they do and also ideologically-compatible. Second, he hooks them in but good with money - there’s no way that these people will want to, or be able to afford to, leave.
That said, it wouldn’t surprise me if a few of his past employees “committed suicide” or something similar, like what happens to the enemies of a certain ex-President who enjoys cigars.
Soros is part of the Marxist Revolution now underway. It gets done just like taking out the garbage or shredding documents.
Before it's all over, China will be able to build a new Great Wall out of human skulls.
