In Genesis 6:5, it is written,
And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
William Golding, author of Lord of the Flies, wrote his allegorical novel with this concept of evil as inherent in the boys stranded on an island away from civilization. Like Jack and the other hunters in Golding's narrative, in "The Most Dangerous Game," Sanger Rainsford degenerates to the "wickedness of man" when his life is endangered. Much like Roger of Lord of the Flies, whose arm at first is restrained by civilization as he casts a stone--"that presposterous element of time"--toward little Henry, Rainsford sheds the vestiges of society and becomes first the "beast at bay," and later, the predator of man.
That Rainsford has had the innate tendency to be predatory is indicated in the exposition of Connell's story when on shipboard, he and Whitney discuss the fear and pain of the jaguar that is hunted. For, Rainsford summarily dismisses Whitney's concern,
"Nonsense,....Be a realist. The world is made up of two classes--the hunters and the huntees. Luckily, you and I are hunters.
Further, as he is pursued by Zaroff and Ivan, Rainsford learns what it is to be hunted; nevertheless, he does not wish to remain as such because he is vulnerable and because he has no sympathy for those who are prey, really. It simply has taken a "most dangerous game" [a hunt] for Rainsford to make of the general the most dangerous of game [the most dangerous prey]. This experience effects the emergence of Rainsford's essential wicked nature that competes in evil against the imagination of General Zaroff. Thus, Rainsford and Zaroff are prototypes for the "wickedness of man" and evil of his imagination.
