There are no villians in this story just grief, saddness and loss for all involved.
God forgive me, but if I was under the condition that the poor veteran was, I hope somebody takes me out back and shoots me in the head. Seriously, I know that is not exactly what happened, but that veteran was going through hell internally and now is at peace with God. I truly believe he is better off. I know it sounds harsh, but I have seen what that disease is like and the longer you “linger” the worse off you are.
You say that now, but I still believe that if you ever become disabled you will stop advocating murdering people for being disabled.
