If pregnant women are obligated to carry a fetus to term to preserve an innocent human life, at personal cost to the woman, why aren’t all men and women required to donate their tissues and organs to save innocent lives?
I mean, what’s the difference between those two situations? In both the case of a fetus and a dying patient, one could argue that an entire innocent human life is at stake. Why is only the pregnant woman obligated to preserve the human life at cost to herself? And why are healthy people not obligated to do so when the opportunity arises?
