The end of the story marks the ending of the story's internal conflict. Explain.

The ending of The Call of the Wild is difficult to understand. It is possible that London chose this ending, because only the death of John Thornton would free Buck from his divided loyalties. Furthermore, killing the Yeehat Indians truly connects Buck to his wild past. He now understands that his dependence on human companionship is false. Dogs do not need humans to survive, for dogs are stronger than humans.
