Yes because the marines have a pathological desire to kill people... PTSD (aka Shell shock) is a very difficult thing to live with. Imagine not just being able to remember your friends dying around you, but being able to hear their shouts of pain, their calls for help, imagine if you can being able to smell their blood, to feel it coating you as they are reduced to a fine pink mist because of an incoming RPG7 or IED. Imagine if you can not only all of this... but imagine it as being like a nightmare when you are awake. Imagine that if you can and you might have some small idea of what PTSD is like. I have known people that suffer from it, I applaud this man in his attempts to reach out to a fellow serviceman who has been to hell, and is unfortunately reliving it every day of his life.
