People struggle with this stuff everyday... getting urges to hurt themselves or other people, and think nothing of it.. its something they would never act on... and then one day... they can't take it anymore. I find it really terrifying that so many people have depression or other mental illnesses and people don't take it seriously.
I knew a guy once who was the nicest guy you would ever want to meet.. The type of guy that would give you the shirt off of his back.. and then he was going through a divorce and snapped... tide his 20 month old son around his chest with a house coat tie and a brick to his ankle and jumped into a swimming hole.
Everytime something like this happens, I think about him. I pray for all the families, even the shooter's.. What they must be going through. Truly Sad.
Great works are performed, not by strength, but by perseverance.
