I've seen what happens to people who are in need of organs first hand. I knew a patient that couldn't get a liver he needed and suffered to his death. Everyone who has the ability to donate a healthy organ should, even if they didn't break the law to begin with. When you die, your rights die too IMO.
Has anyone ever read the book, "Johnny Got His Gun"? Many people see it as an anti-war novel, but it goes beyond that. In the book, the main character, Johnny, gets hit with a mortar and miraculously lives. The doctors at the station were all thrilled and proud that they could save a human life that was so close to death. They saved him, but he no longer had a face, arms, legs, mouth, his reproductive organ, etc. He was simply a torso of flesh with a neck upholding the flesh that contained his brain. He couldn't talk, taste, smell, see, hear...all he could do was feel his torso against the sheets and move his faceless head a little. Finally, he discovered that he could bang his head against the wall/bed rest and communicate in Morse code, "S.O.S." A knowledgable nurse recognized the attempt and responded likewise by tapping his body. He eventually asked for them to kill him. The nurse asked the doctors and they told him that it wasn't in their policy; they weren't going to let him die.
Sorry for the book summary, just hearing about those transplants made me think of it for some reason--completely unrelated I know. But with how many people need transplants, stem-cell research pushing the boundries of medicine, etc. I can begin to understand why some people are so edgy about how people are saving lives. Sometimes death ends suffering, sometimes preventing death and saving life ends it.
