What about people who have HIV or AIDS? Would they be able to donate their organs? I don't think that's a positive attitutude (or very altruistic) that I can only give my organs to someone who agreed to donate to donate theirs.

My mother was the recipient of an organ donor and I am registered one as well. However, I understand that not everyone is able to give the gift of life and the reasons are not always for selfish ones either.
