Soldier kills his own men

An American soldier killed 5 of his own peoples recently in Iraq. No details as of why he did it has not been released yet, so I have no explanation other than mentally disturbed or paranoid. A lot of people are saying that all the soldiers just need to come home and end the war. I somewhat agree that the war should end, but I would rather they get evaluated and assessed before coming home. These soldiers has seen a lot and been through hardcore training, they are a deadly weapon sent across the world to kill. Now if they all come back to the states, where are they going to work, unemployment is already sky high, especially for men. That is why its best to get them help and prepared for the big transition of coming home. Some soldiers commit suicide months after returning home from the states because they couldn't handle the transition. This is a really bad situation, but i really do they come home safely mentally and physically. RIP to the 5 soldiers.
