Hurtling down the road in excess of the speed limit is also dangerous. Both actions have some probability of killing someone over a long enough time horizon. What's the threshold? Or are most people in cars also essentially murderers as well?

You misunderstand.

It isn't 'all the drivers' fractionally at fault (others can quibble about that), it's the people who create the moral hazard. The car industry and politicians that decided that the ungoverned car, the road, and the parking lot will be the only way to traverse Dallas or LA lo those many years ago, the ones that affirm that system with 'one more road' using tax dollars year after year, knowing that more people will die as a result. https://en.wikipedia.org/wiki/Motor_vehicle_fatality_rate_in... <- the line goes up.

They have a duty of care as representatives that they are failing to meet. Compare that to cities in Europe or the North East. When you make policies that serve the few and sacrifice the bodies of the many, that act is violence.

Likewise, with PE. When they intentionally understaff a hospital, no single doctor is responsible for killing the patient that died bleeding in the waiting room. It is the choice that we allowed that PE firm to make. Are you comfortable with a fresh MBA using excel to ensure that your local hospital should have four less doctors than strictly necessary to treat you in a timely manner? Society doesn't need to be organized this way, we can and should demand better.

Imagine the reverse, a municipality decides to privatize their water and sewage treatment, but puts no restrictions on the results as long at those wealthy enough are not inconvenienced. This is precisely how you get Flint. Or redlined cities that put the 'undesirables' in industrial waste parks. These acts are violence.
