In the novel Lord of the Flies by William Golding, Roger represents the evil side of the stranded boys, and the terrible lure of undiluted power. Autonomy really is about self-government while Roger demonstrates little control of himself or any kind of government except power. From the destruction of sand castles to the first rock throwing at Henry, Roger allows his worst impulses to govern his actions. When Jack rebels and leads his group away from the government of Ralph and Piggy, Roger follows Jack and his quest for power. Roger participates in whatever Jack wishes, and values the power Jack demonstrates. Though Roger doesn't always agree with Jack, he still follows the descent into the madness of the island. Roger is the one who pushes the boulder which kills Piggy, the voice of reason, and smashes the conch, the representative of truth and civilized government. Roger does feel gleeful and triumphant at the destruction, but because he feels powerful himself. Power is his prime motivator, for Roger values power above all else, and his evil actions demonstrate his lust for power just like Jack.
