I Know why Mass Shootings Happen

And so do you. Someone gets mad out of their mind.

This is not a complete answer, of course, we also have to say why he (and they are always men) acted this way. What drove him to it?

Asking why does not condone any violent action, and does not explain any benevolent action. But as thinking beings, we need to ask this vital question, why?

The usual answer is "I don't know," which is fair enough if we do not follow it with "And I don't want to know!"

Which implies that we really know, but don't want to admit it.

This hidden answer is that life is frustrating. Needlessly so.

And this is a very common experience.
