How does Buck's view of humans change throughout the story?

Buck's evolving perspective on humans throughout the story is one of the key themes in "The Call of the Wild." Initially, Buck is naive and trusts humans, viewing them as protectors and providers. However, as he experiences the brutal realities of life in the wild and the harsh treatment from some humans, he becomes increasingly aware of their capacity for cruelty. This transformation leads him to develop a wariness and critical outlook towards humans who display violence or indifference.

At the same time, Buck also encounters kindness from certain individuals, such as John Thornton, which fosters a complex understanding of humanity. He learns to appreciate those humans who exhibit compassion and care, contrasting sharply with the cruelty of others. This duality in Buck's feelings towards humans indicates a matured comprehension that not all humans are the same. Thus, he evolves into a character who can discern between those who show kindness and those who embody cruelty, making the answer valid as it encapsulates both his wariness and appreciation for humans.
