Richard Connell in "The Most Dangerous Game" suggests the theme of legitimate murder. His character Rainsford believes animals are inferior to men because they cannot feel, thus justifying hunting. Another character, Zaroff, thinks hunting men is more interesting than hunting animals, because humans have the power of reason.
On the other hand, Ernest Thompson Seton's "Lobo the King of Currupaw" about a the author's personal experience hunting wolves, tells the story of Lobo and Blanca, the man's struggle to hunt them, and describes Lobo's sorrow after Blanca's death. The story then lead to a conservationist movement for the protection of wolves.
