How does the irony in The Most Dangerous Game connect to the theme of man vs. nature?

Zaroff is a man of contradictions. While being an extremely "civilized" man in the sense that he is knowledgeable about aspects of high culture, he also presents himself as barbaric. The entire island is a contradiction. The lavish house stands starkly against the dark jungle where the hunt occurs. In some ways, Zaroff can be seen as a stand-in for humanity. The same irony that Zaroff presents in "The Most Dangerous Game" is also present at the pinnacle of civilization today - highly advanced and educated civilizations still murdering each other over land and resources.
