A Separate Peace Dealing with enemies has been a problem since the beginning of time. “I never killed anybody,” Gene had commented later in his life, “And I never developed an intense level of hatred for the enemy. Because my war ended before I ever put on a uniform, I was on active duty all my time at Devon; I killed my enemy there.” In A Separate Peace, by John Knowles, the value of dealing with enemies is shown by Gene, who was dealing with few human enemies, but his emotions created far greater rivals than any human could ever posses. One of the enemies that Gene created for himself was jealousy. Gene was jealous of everything about Finny.
