Zaroff thinks it’s foolish and old-fashioned that Rainsford values human life even after fighting in the war.
Explanation:
In this story, we learn that both Zaroff and Rainsford are hunters. In fact, the two characters bond over this at the beginning. However, as the story progresses, we see that the two have very different views on the value of life. Rainsford does not value the lives of animals, which allows him to be a hunter. However, he does value human life, and he believes these two to be very different. On the other hand, Zaroff believes all lives to be the same, and he is therefore comfortable hunting and killing humans. Moreover, he believes Rainsford to be "naive" and "droll" for caring about this distinction.
