Guys of GAG, What would you do if your Ex wife, who cheated on you, needed your bone marrow to live, or worse, her affair partner needed it?

Its a hypothetical, but apparently its something that happened in my home town. A man was on the donor registry, and found out, though it was supposed to be anonymous, that his marrow was going to his ex wife's lesbian lover. He removed him self from the donor registry as a result.

I am not sure what i would do in that situation. I may be angry in that situation. But i could also hold it over them that i saved their life. On that same token, its supposed to be anonymous so i could simply refuse and let them die. Im not entirely sure i could let someone die for revenge though.

What would you do?

After discussing with my wife, we both feel like he did the right thing, letting the cheater die.
