General Zaroff leads a luxurious life of sport (and murder) in isolation on his own private island.
Zaroff lives in a “palatial chateau” on a small island called Shiptrap Island. He eats gourmet food, and “the table apointments were of the finest--the linen, the crystal, the silver, the china.” Even Zaroff’s guest room is huge, with a bed big enough for six men and suits by exclusive London tailors.
Since Zaroff lives alone on an island where no one who visits ever leaves, he can get away with pretty much whatever he wants. There is no law or government there. Zaroff makes his own laws, which include keeping things luxurious.
"We do our best to preserve the amenities of civilization here. Please forgive any lapses. We are well off the beaten track, you know. Do you think the champagne has suffered from its long ocean trip?"
What Zaroff does not care about is human beings. He hunts men for sport, and has the best dogs and hunting gear. He does not see anything wrong with killing for fun, and he continues to do so until Rainsford falls off the yacht and puts a stop to it.
