This is the first thing everyone thinks about before donating a kidney, I think. I think some questions to add to this list: What if your kidney isn't compatible with that of your family member, and they'd have to rely on a stranger's donation? How would you then feel about never having donated in the past? What if you donate your kidney to a parent, only to find that a year later your child needs your kidney? What if you donate your kidney to a family member and they later end up ruining your life? There are so many "what-if" scenarios possible. Ultimately I think it boils down to probabilities vs effectiveness.
