No, the person died because the fluid buidup killed her; but since you refuse to accept the basic premise of my example, you are not willing to discuss this rationally.
Cases like the one you describe are difficult, and I don't have all the right answers. What I would say, however, are that there is a major fundamental difference between ordering that someone be rescued from a condition stemming from natural causes, from accidental causes, or from deliberate causes. I think it entirely reasonable that a governor be given more authority over cases in which an imminently-fatal condition is the result of deliberate action than one in which the fatal condition is not the result of deliberate action.
BTW, on a related note: is a DNR binding on someone upon whom a murder attempt has been made?
