How does zaroff treat his visitors and what is the purpose?

Zaroff treats his visitors, particularly Rainsford, with a deceptive charm, initially presenting himself as a gracious host. However, this facade masks his true intentions, as he views them as prey for his twisted hunting games. The purpose of this treatment is to lure his guests into a false sense of security, making it easier for him to reveal his sadistic nature and engage them in his lethal sport. Ultimately, Zaroff's hospitality is a means to satisfy his obsession with hunting humans.
