Final answer:
Examples of greed in 'The Pearl' include Kino's dream of a new life due to the pearl, the Doctor's newfound eagerness to treat Kino's son because of the pearl's value, and the Pearl Buyers' attempt to buy the pearl at a price far below its worth to maximize their own profit.
Step-by-step explanation:
In John Steinbeck's novel 'The Pearl', the theme of greed is central to the narrative. The character Kino exhibits greed when he finds the magnificent pearl and allows it to cloud his judgment, leading him to desire more than just a cure for his son's sting, but also a complete transformation of his family's life, disregarding the potential consequences.
The Doctor, upon hearing about Kino's pearl, suddenly becomes very interested in treating Kino's son, not out of a sense of duty, but because of the pearl's value and what it could mean for his own wealth. Lastly, the Pearl Buyers illustrate greed through their conspiracy to offer Kino a much lower price than the pearl is worth, in an attempt to enrich themselves at his expense.
