Ahhh that is often a common thread seen in bad mountaineering decisions… goals. Whether it’s on Everest or some backyard hill. Setting a goal and the desire to complete the goal vs. turning around or saying nah, this isn’t the time… that has been at the forefront of many mountain accidents over the years. From skiing to backpacking, the desire to complete the mission or objective has killed more people in the mountains (sometimes the conditions and timing just isn’t right) than any other human factor.
It can be very hard to accept defeat and turn around. Though it’s not defeat… staying alive should be considered winning.
I’ve read many mountaineering books from people climbing high summits and that internal struggle to realize it isn’t happening and to turn around is often the biggest mental hurdle. That Everest disaster 2-3 decades ago was all because of that desire to complete the goal of summiting. They pushed past the point of no return, it got late, dark, and it killed people.
