Who's more likely to snap someone who doesn't care or someone who does care?

[Mister Obvious]

I think if it was so easy to determine who was gonna snap based on these factors, we wouldn't have any of these unforeseen violent events in the world. Not on a small or large scale.

I think a lot of factors go into the tendency to snap, and some of them are definitely calculable. But they aren't things like plans that fell through, or people not caring about stuff etc.
