hat kind of
Because it takes only 1 mistake to get you killed...
You take your atc, clip it wrong and belay your leader. He don't fall!!!
You still make a mistake, and nothing happens.
In the example that I gave from recompense, I describe that kind of situation where mistake was done and nothing happen.
As you don't see the mistake that you do as you climb....it is true that the only important mistake is the one you will killed you...for you. Other climber, if they are wiser, instead of using Krakauer mentality, will try to see the danger and understand where they are doing mistake...and in most situation, there is always a solution to get out of the problem, and be safer, and make dad and mom happier!!!
