Both boys begin with a certain admiration for each other but the relationship quickly becomes antagonistic. Jack could not handle not being elected chief. Even when Ralph appeases him by giving over control of the choir, Jack remains rebellious and defiant. Jack uses his skills of projecting fear to manipulate situations that make Ralph look weak. I'm not entirely sure if Jack knows exactly why he hates Ralph. At one point in the story, Ralph asks Jack, "Why do you hate me?" It is telling that Jack does not answer because he really does not know. Jack hates anyone in authority other than himself. While Ralph is alive, Jack knows that he can use Ralph as an enemy-figure. Jack must publicly destroy Ralph's credibility if he (Jack) wants control.
