Many soldiers, and I know a few who are out now, chose the military to help pay for college and/or to get out of a troubling environment. Maybe they lost the breadwinner of the family...lots of possibilities besides an intent to commit cold-blooded murder.
Or maybe, like my sister-in-law who is at VMI (a military college) with hopes to be in the Air Force one day, she has 20/20 vision along with the smarts, and is actually ambitious enough to be a pilot. She's also one of the sweetest people you'll ever meet. You do know that many commercial airline pilots are retired Air Force, right? Most of them are not out to string up a bunch of babies on a clothesline.
