For me, and this is my own personal belief, I would feel that if I didn't do all I could to help another person who was in a life and death situation, at the cost of organs that I would have no use for, I would then have to justify this to the higher power at judgement day, so yes I am registered as an organ donor, my DH is an organ donor and if ever I was faced with the tragedy of having to donate my child's organs, I would.
