If given a chance they will kill. To obtain that level of wealth one generally has to have a sociopathic level of lack of empathy. Maybe not all are like Trump and itching to blow people up and put people to death. A lot are probably less actively bloodthirsty (thankfully) but at the same time have no issue taking away your health insurance, your income, your housing, etc if it impacts their bottom line even though they already have enough resources to last 100,000,000 lifetimes in extreme excess.

“Oh but if they let these things change they would lose their wealth” exactly - when it comes down to it, they would rather leave you to die than risk losing their obscene wealth. So this is violence, and therefore violence is an appropriate response, especially when the state continually and repeatedly fails over decades (arguably from its inception) to rein them in.
