 Assuming a potential donor would give valid consent, how far would that justify retrieval of organs? The “do no harm” rule implies that people should not be harmed even with their consent although, as was said earlier, some living organ donation may not harm the donor all-things-considered. Suppose a man wanted to donate his second kidney to his second son, having already donated a kidney to another son, thus paying the price of a life on dialysis. Suppose a parent wanted to donate her heart to her child, thus causing her own death. Would transplant teams act wrongly if they took organs in such cases? And—what is a separate question—should they be allowed to?
