because it gives him the excitement after he kills them also because he feels that animals aren't as fun and lastly because he is a psychopath.
Civilized people do not hunt other humans for fun/sport.

general zaroff bought the island to hunt his new found prey, humans
Zaroff prefers to hunt humans because it provides more of a challenge. Humans can think logically develope fully formed ideas and contemplate next moves. Animals go upon only instinct. Humans make for the tougher hunt.
hunting
Genral Zaroff's main reason for preferring to hunt human beings rather than animals is because animal has no reasoning (e.g you shoot an animal he either chooses to run or charges straight at you and you can shoot it and kill it easy which is no chalange for Genral Zaroff). A reason he chooses to hunt humans is because they can reason with you and are more of a challenge (e.g the humans General Zaroff hunts can build weapons and try to kill or attack Genral Zaroff, which Genral Zaroff think is more fun then an animal charging against him).
General Zaroff lured humans to his island by shipwrecking passing vessels and then inviting the survivors to his mansion. He would win their trust as a fellow hunting enthusiast before revealing his deadly game of hunting them for sport on the island.
hunt him
Zaroff justifies his hunting of human beings by believing that he is superior to them intellectually and therefore has the right to hunt them for sport. He sees his victims as challenging prey that can provide him with a greater thrill and excitement than animals can. Zaroff's twisted logic leads him to view hunting humans as a natural extension of his pursuit of the ultimate hunting experience.
General Zaroff hopes that Rainsford will participate in his twisted game of hunting humans called "The Most Dangerous Game." He wants Rainsford to become his prey and provide him with a challenge during the hunt.
Zaroff studies Rainsford to assess his skills and intelligence, as he sees Rainsford as a worthy opponent in his twisted game of hunting humans. Zaroff wants to determine how challenging the hunt will be and whether Rainsford will provide the excitement and satisfaction he craves.
He does that for a sport.
General Zaroff proposes a hunt, but only the General will be hunting because Rainsford will be his prey.
