Organ donation

Actually, here's one for you lynx. Say a close relative contracted a medically incurable condition that was imminently life threatening. You, by some form of bizarre providence are the only match for them to have a kidney transplant, the only procedure that will save them from a premature death. Would you reject their request for an organ that you can quite reasonably spare?

I honestly don't know. I'm missing bits of my body already so don't understand where this fear/feeling comes from.

Its also they wouldn't want my kidneys
