I hope people are never denied such opportunities based on the opposing rationale that they're unsafe. Sometimes a self-unactualized can be worse than death.
Like many things in life, it probably has more to do with the weather conditions and the phase of the moon than your abilities as a person. To derive your self-esteem from external things which are almost entirely outside of your control makes no sense to me.
Changing weather is part of the risk, but I doubt anyone heads out knowing a storm is on the way.
Self-actualization for many is not about standing out in comparison to others, it's about simply doing the experience itself for oneself.
You could say that about sailing across the Atlantic solo too but it wouldn't make any sense. It's all part of the journey and the accomplishment.
The "abilities" you speak of also encompasses emotional fortitude, decision making, pushing yourself, etc. The challenge doesn't need to be about being a world class mountaineer. For most - it's reaching a personal best and accomplishing something that scares you. That can make you feel even more alive.
When I rest I feel utterly lifeless except that my throat burns when I draw breath...I can scarcely go on. No despair, no happiness, no anxiety. I have not lost the mastery of my feelings, there are actually no more feelings. I consist only of will. Messner on the first solo ascent of Everest

Mount Everest: Bodies of four climbers found in tent http://www.bbc.com/news/world-asia-40025553
Yes, he took drugs but then again, who didn't in a 4 day bike race.
21 days for the Tour de France, most other races in the season are 7. 4 days is a really nice amatuer stage race :)
Regardless of the ratio of Sherpas-to-tourist deaths, almost every year a few Sherpas die performing the real dangerous work of running up and down the mountain making the climb manageable for the tourists, installing ladders and carrying oxygen to base camps and such.
So for the tourist, the death rate is probably much lower, likely in line with other dangerous activities such as skydiving, base jumping or race car driving.
