This is a question concerning the main plot of the story. The concept of survival is at the center of this tale. Rainsford is put in a position where he has no choice but to relay on his skills as an expert hunter to stay alive and survive Zaroff's "game". However, as the story moves on, Rainsford becomes more and more desperate until the end, where he has used up his last trick and is without any protection with the General on his trail. He eludes Zaroff by flinging himself off the cliff and into the Sea. However, he does not stop. He then hunts Zaroff stating that he is "still a beast at bay". Even after Zaroff congratulates him for "winning the game" Rainsford wants revenge and kills him, thus becoming the hunter.
