Mountain climbing at best is still extremely dangerous. You cannot eliminate the possibility of dying up there no matter how good you are or how experienced you are. There's always x percent probability that something unexpected will happen and snuff out your life instantly, and there won't be a thing you can do about it.
I used to have a close friend that loved climbing big walls, like you see in yosemite. On one climb in the Andes they were on a wall, and he looked up and saw a ping pong ball sized rock falling towards him from way up above. As it got closer and closer, it became apparent that that little rock was the size of a box car. It missed him literally by a few inches. Not for me, thanks.
