Answer:
Rainsford is an avid hunter at the start of the story, believing that man is superior to animals, that his prey has no feelings, and that hunting in general is just a game. He believes that the world is divided into two parts: the hunter and the hunted. This opinion changes when he discovers Zaroff intends to use him as prey. When Rainsford accepts that he must play Zaroff's "game," he begins to resemble Zaroff. When he kills Zaroff's dog and then Ivan, he becomes a serial killer. Rainsford kills Zaroff by the end of the story, and we don't know if he has become like Zaroff.
