The tricky thing here is many are actually killed intentionally. And the killers escaped from that and, instead, were ruled as unintentional. Justice is missing here. That's why the whole damn calculation is valid. I know a lot more similar calculations, driver vs pedestrian, doctor vs patient, kid-robber(yes, many parents are worrying about kids being robbed in front of you, that's not a joke), the list can go on and on. I'm from China. And that's why I left. People in China always debate on wrong factors or they are just not brave enough to talk about it publicly and get used to heavily-self-sensored so that new fake self-consciousnesses take control.

But there's a difference between avoiding helping someone and intentionally taking action to kill someone.

Yes, of course. But the economic calculus is similar. The economic disincentive is huge.
