Yeah, but my point is that we already know enough to know that he has had pretty good progress so far. None of the organs are critical (or he wouldn't have survived - they may recover, or they may need to be replaced or sustained with medicines - a lot of organs can be dealt with that way, and your life is still quite worth living. People who can't walk still want to live their lives. Brain damage is the big one - but there are indications that he doesn't have much if any - relatively speaking. Survivor guilt and nightmares - so many people have that, and life is still worth living for them. Survivor guilt and he will never walk again and some minor brain damage - I think that's still a life well worth living - people who have that think their life is still worth living.
I do know what you mean - I watch a lot of the medical channels, and when you see a burn patient come in, or someone with severe brain damage that will leave them vegetative or an infant for the rest of their life - sometimes it's pretty clear that survival is not the good option there - but they can do a lot these days. I agree with your general point, but in this case there's plenty of indications that surviving was the good option this time.
