Who says its considered an illness of the brain? Thats retarded. Its most definatly not. Because you can commit suicide for a 10000000 reasons. If I got bit by a zombie for example I would blow my fucking brains out. Thats a choice. If I am fighting in Iraq and I am wounded and I know there is a million dollar price on any living Americans heads by the terrorist leaders so they can decapitate me in public, better believe I am pulling the trigger on my own ass, or better yet grip a grenade and wait for a terrorist to try and grab me then BOOM to hell we go.
