There is an important point I have never heard spoken, relating to this subject; I accept responsibility for the life and death decisions I have made, and will have to make in my lifetime. I do not kid myself, and believe that only fate, or only luck or only God makes these decisions. I have already had, and I suspect will have again to make a life and death decision in my lifetime. We have parents, children, brothers, sisters - any of whom may live or die at our decision to "pull the plug" one day. That is a life and death decision, and I would NOT shun the responsibility. Sometimes humans are faced with even more direct life and death decisions.
