List of things I'll never understand

I have a new entry for my list of Things I'll Never Understand. I don't care how long I live. I'll never understand how any man or woman can strap on pounds of explosives with the idea of detonating them in a place filled with people and think that by doing so they are committing a righteous, justified act, an act that will eventually bring peace.

Question: How is murdering innocent people, including children, ever justified?

Answer: It is NOT.
