What does Buck finally feel about his role among the wolves?

Buck's journey throughout the novel leads him to a profound self-discovery and acceptance of his primal instincts. By the end of the story, he recognizes and embraces his role in the natural order of the wild, finding a sense of belonging among the wolves. This acceptance is a culmination of his transformation from a domesticated pet to a creature of the wild, adapting to the laws of nature and understanding his place in the pack hierarchy.

The idea of feeling at home signifies that Buck has not only accepted his instincts but has also integrated into the wolf pack, affirming his identity as a creature of the wild. This sense of belonging contrasts sharply with feelings of conflict or uncertainty, superiority, or rejection, which would indicate a disconnection from his surroundings or a struggle with acceptance. Buck's journey highlights the importance of connecting with one's instincts and the wildness that lies within, ultimately finding harmony with his new family in the wilderness.
