It is debatable whether or not Rainsford is a dynamic character in "The Most Dangerous Game." Through a discussion with Whitney during the exposition of the story, we learn that Rainsford has no concerns when it comes to how an animal feels when it is being hunted. Ironically, he later becomes the hunted to Zaroff, the hunter.
Through third-person omniscient point of view, the reader witnesses Rainsford's feelings while being stalked by his aggressor. At the end of the story, Rainsford wins the "game" by killing Zaroff. Whether or not his opinion on the feelings of animals has changed is yet to be known, as the story ends abruptly with Rainsford having a good night's sleep in Zaroff's bed. We would hope that because he was treated like an animal, he has developed some empathy.
