And when the family decision is to keep the poor child hooked up to the machine regardless of what it does to him? Forcing doctors to keep him sedated for weeks or months or longer, and upping the medication as they go along so he isn't suffering, all in a forlorn hope that a miracle will occur and he will be suddenly cured? When should the voice of reason enter into the picture and say, "Enough" and let the poor child pass in dignity and peace? And who should be that voice? Those who know what he's going through or those who are prolonging the suffering?
If the parents are truly Christian then they shouldn't fear death, for they should know that their son is going to a better place where he won't suffer anymore. They shouldn't promote the end, but neither should they extend it for their own feeling's sake. Their son is gone. Let him go.
I’m really not sure what point you are trying to make. That there should be some sort of authority figure dictating health care decisions?
