At the end of the story, the man decides that he's been acting shamefully by trying to make an impossible run for the camp. For the first time in the story, he's completely given himself to panic, but it's not long before he regains control and decides to die with dignity. Despite his blunder in traveling alone, you have to hand it to the guy for how well he handles his terrible situation. In this moment, he's perseverant, unflinching, and humble, too. He knows that he's relied too heavily on personal experience rather than instinct, and when it comes to the Yukon, you don't get the benefit of gaining wisdom when your first experience of something is also your last.
