You have made an implicit choice to say that the loss of some number of people in one event is equivalent to the loss of the same number of people in multiple events. And you have ignored the effect of whether people perceive themselves as having control over events.

However, that's not how people think. Single events where lots of people die are much more interesting than multiple events. Furthermore, events where the victims were not in control of the situation are also interesting.

This is what causes people to get upset when a hundred people die in a single airplane accident, or a single building bombing, or a single chemical plant explosion. It doesn't matter that coal kills more people than nuclear energy, what matters is that the coal deaths happen one at a time spread out across the world, and the miners could have not gone into that line of work.
