From a moral standpoint, hunting humans is clearly unethical and immoral, and Rainsford's initial reaction to refuse to participate is understandable. However, as the story progresses, it becomes clear that Rainsford's only chance of survival is to participate in the game, and he ultimately decides to do so. One could argue that he made the right decision, given that he was able to outsmart Zaroff and survive. On the other hand, one could argue that by participating, Rainsford was implicitly endorsing and perpetuating the cruel and inhumane practice of hunting humans, and that he should have refused to participate on moral grounds. Ultimately, the decision of whether or not to participate in such a game would depend on an individual's personal values and beliefs about what is right and wrong.
