Your first mistake is thinking that people like Thomas actually feel empathy for other people that aren’t them. There’s been studies on this - wealth, especially extreme wealth, physiologically changes how your brain processes things like empathy, altruism, etc.
In fact, it would have to be the DoJ or Congress that did so - Biden could order the DoJ to stop, and arguably could have anyone in Congress killed or jailed without trial by stating that they presented a clear danger to democracy by trying to impeach him.
