I'm not gonna say that murder is right or anything. But, people in power can and often will threaten other people with their lives and get away with it. Elon Musk is a good example of that. Yes, we don't know have any proof of him killing people, but he can casually and "as a joke" say that other people should be assassinated.

The problem isn't that a CEO was killed, the problem is that it has gotten to that point, where so many people get killed overall, and the big powerful people don't give a fuck. But when suddenly someone "important" gets killed, then it's a big problem.
