General zaroff explained that he had grown bored with hunting and was looking for a challenge why is rainsford the perfect adversary for zaroff

Rainsford is the ultimate hunter. He's smart, observant, and he knows how to anticipate his prey. All of these things make him the perfect adversary for Zaroff. The only difference being that instead of acting as the hunter, Rainsford will have to change his strategies and survive being hunted.

Hope this helped!

now you can make him brainleist.
