A climber frames danger as a private bargain with his own life, but the real cost of a death falls on parents, spouses and partners who never accepted the risk. The freedom to risk yourself is therefore not self-regarding. It spends other people's futures without their consent.
After a partner dies, survivors build an explanation of the accident, such as a technical error, bad luck, or 'he would have wanted to die this way.' The explanation protects the survivor's ability to keep doing the activity. Roberts treats these accounts as psychological defenses, not truths. He shows how they turn a death into a lesson so that the pursuit can continue unexamined.
The heightened clarity, focus and aliveness climbers seek is produced by the real possibility of dying. Removing the danger removes the reward. The same mechanism that makes the activity meaningful also guarantees its casualties, so its value and its cost cannot be separated.
