Bill,
Abyss? I doubt that!
I think you would find that blood, for the purpose of a life threatening trauma or surgery, would always be readily available. If the fact that your ability to give blood provides you with a sense of "having beaten this disease" more power to you. If that person dies from YOUR strain of cancer then that is a moral decision you will have to live with. Me, I don't get it. You would risk infecting someone with cancer?...........I still don't get it. I think I'll go to my books, but in NY, I sure hope that would be a crime! I believe it is an issue with other blood borne illnesses.
