Most of our society may not, but that shouldn't stop us from feeling for the people we do hear about.
Let's say the shooter died in a car crash on the way to work, having every intention of shooting up the place. But no one knows except him.
Everyone would be like "oh, that's so sad!".
But then the gun is discovered, and a suicide note saying what he'll do. Everything changes. What if the people he shot, were the people that made him do it in the first place? Is it so sad when the people who push him over the edge, get shot? I mean, they induced it.
