What is a good "man vs. self" conflict in "The Most Dangerous Game"?

There obviously is no conflict within General Zaroff: He has already practiced his new human hunt, and he has no qualms about killing men instead of animals. The conflict comes with Rainsford. He is given the choice of being killed by Ivan, Zaroff's assistant, or attempting to elude Zaroff as the prey of his hunt. Rainsford chooses to survive, at least for the time being. Although Rainsford, unlike Zaroff, has no thirst for human blood, he does what he must in order to survive: He kills Ivan and several of the dogs as he attempts to elude Zaroff. Perhaps his greatest inner conflict comes at the end of the story, when he returns to Zaroff's mansion and decides to begin a new hunt himself. The urge for revenge must be overwhelming, and we can assume that he feels little guilt when he turns the tables on Zaroff, because afterward, he sleeps soundly and happily in Zaroff's bed.
