Which character said, "If you strike that dog again, I'll kill you"?

The quote "If you strike that dog again, I'll kill you" is attributed to John Thornton, a key character in Jack London's "The Call of the Wild." Thornton is depicted as a compassionate and strong individual who forms a deep bond with Buck, the main character and a dog who has been mistreated and abused by others.

This moment highlights Thornton's protective nature, especially toward Buck, who has suffered greatly at the hands of those who do not understand or respect his worth. Thornton's declaration reflects themes of loyalty and the idea of standing up against cruelty. It's crucial to his character development, as it establishes him as a figure of kindness and bravery in stark contrast to the harshness Buck has experienced with previous humans. This pivotal interaction illustrates the turning point in Buck's life, where he finds not just a master but a companion who truly cares for him.

Buck's relationship with Thornton represents a healing journey and an alliance built on mutual respect and love, contrasting the abusive relationships he had previously endured. Thus, Thornton’s assertiveness in defending Buck reinforces his role as a significant and moral presence in the narrative.
