Rainsford has mixed feelings regarding the animals he hunts, depending on where you are at in The Most Dangerous Game. For instance, in the beginning of the story, while Rainsford is on board the boat, trading stories with his companion, he feels that the animals are simply prey to be hunted and ultimately killed. All of this, of course, changes as Rainsford progresses through the story.
As Rainsford encounters General Zaroff, his opinions slowly begin their metamorphosis, as he eventually becomes the hunted in the game with Zaroff. He becomes as desperate as his previous prey, as he is hunted down like an animal by Zaroff.
However, it is very important to note that at the ending, Rainsford treats General Zaroff in a similar vein, as he must act swiftly in order to win the game. He becomes what he ultimately hates, which is the new and future Zaroff.
