Why not get into euthanasia? It's legal in three states. Appearantly there are some people that see any conflict with doctors helping him end his life with dignity. Why not just transport him to one of those states? Then debate over. He's dead. No doctor feels like they broke some over valued oath. Everyone is happy. Oh yeah and we get some shiny new organs to research on.
But then there's a whole new argument over whether doctors will take organs harvested from someone who died by assisted suicide (guilt by association), and for that matter trying to find a form of euthanasia that's both relatively pain-free AND will not damage his otherwise viable organs.
Honestly, that's about the best way I can see them going about it. Otherwise, in the eyes of the doctors, letting him suffer is still doing a lot less harm than assisting his death. Or, again, it's more likely about the politics of how quickly they'd get fired and otherwise ostracized for going along with it. Unfortunate, yes, but a doctor at Emory or any other major hospital who aids him in his wishes would be treated as a leper by the medical community. If not stripped of their credentials and given prison time, really. 3,000 miles to the west and it might be a possibility (Cali and Oregon specifically), but not in the deep South.
On an irrelevant note...hey, he's only an hour from here! And no, I'm not going over to his house to help him out, so don't even think about joking.
