Not to single you out P.C., but I just wanted to make a point and this is a handy quote.
JW's believe that when you die, there is nothing. Then when judgement day arrives, the faithful are resurrected to live forever in Paradise (like the Garden of Eden). The unfaithful are resurrected, judged and then destroyed.
Taking in blood is a mortal sin to them and by allowing their children to live a few more years now, they may be sacrificing eternity, (assuming that their beliefs could be correct).
To go one step further, remember Terry Schivo? It was the religious nutballs keeping her alive. By all accounts, she was not even a religious person, when she was able to conciously be one.
Personally, I'm not sure what I would have done if I was the doctor in either case.
