why is beauty smith important and what happens to him?

Beauty Smith is a very ugly and cruel man who tricks Gray Beaver into selling him White Fang in exchange for whiskey. He turns White Fang into the "Fighting Wolf" by constantly tormenting him, both physically and emotionally. He has White Fang fight other dogs in order to earn money. I don't think anything happens to Beauty after Weedon Scott, stops the fight, and forcefully buys White Fang from him (Beauty Smith).
