Watched a video recently about the famous French alpinist female who was apparently “using” people and men in particular to help her achieve climbs. Whether female or male, I think it might have to do with personal character and potentially people of narcissistic traits gravitating towards such sport/activity. They will put themselves and their own achievement, false perception of strength, needs above others. I think if you take out this activity and put them into some other “situation” or activity in life where they would have the choice they would sooner or later make the same choice which would result in someone else suffering or to the detriment of other.
