Jack represents evil and violence, the dark side of human nature. A former choirmaster and "head boy" at his school, he arrived on the island having experienced some success in exerting control over others by dominating the choir with his militaristic attitude. He is eager to make rules and punish those who break them, although he consistently breaks them himself when he needs to further his own interests. His main interest is hunting, an endeavor that begins with the desire for meat and builds to the overwhelming urge to master and kill other living creatures. Hunting develops the savagery that already ran close to his surface, making him "ape-like" as he prowls through the jungle. His domain is the emotions, which rule and fuel his animal nature.
