However, we celebrate the kindness of a stranger who donates a kidney to a young child. So, clearly, it is not the transfer of the organ that outrages us – we do not think the donor is misinformed about the value of their kidney or is being fooled into parting with it.
Nor, I think, do we have concerns about the scruples of the person selling the organ – after all, they are parting irreversibly with something that is very dear to them for a price that few of us would agree to. I think part of our discomfort has to do with the circumstances in which the transaction takes place.
