A ton of people it seems, have pulled the plug on their loved ones, or not so loved ones, and they are trying to assuage their guilt. A ton of other people just have no religious beliefs about life.
I think the biggest problem I have with this is that the one making the decision moved on with his life. If a couple is going through a horrific divorce with child custody, would it be right to have the other spouse in charge of a life and death decision? I don't know all the circumstances, but there sure is an odor in the room.
