They have heads filled with more horrors than you can imagine. I feel so bad for them as I have a few vet friends, most of whom have combat experience from Iraq and Afghanistan. Ive heard all the horror stories and watched the toughest guy I know break down in tears over what he did to people. One friend accidentally shot a child dead and has to live with that until he dies. They all came back different. They all moved away to the country side far from cities. They all know one or more fellow veterans who took their life because they could not live with these horrors. They use these men and women to do their vile dirty work then throw them away when they're done.
