I’d rather help try to save a life however futile than reach the top of a mountain for nothing but a sense of achievement.
Well, this is the thing. Some people, a small number, do help. It's personal choice. I've never been higher than 5,000m so I have no direct experience but I suspect I'd be a pass on by sort of chap.
For what it's worth, everybody is dying at that altitude. You're on a countdown timer and you don't know when yours will run out.
