Jack expertly uses the beast to manipulate the other boys by establishing the beast as his tribe’s common enemy, common idol, and common system of beliefs all in one. Jack invokes different aspects of the beast depending on which effects he wants to achieve. He uses the boys’ fear of the beast to justify his iron-fisted control of the group and the violence he perpetrates. He sets up the beast as a sort of idol in order to fuel the boys’ bloodlust and establish a cultlike view toward the hunt. The boys’ belief in the monster gives Lord of the Flies religious undertones, for the boys’ various nightmares about monsters eventually take the form of a single monster that they all believe in and fear. By leaving the sow’s head in the forest as an offering to the beast, Jack’s tribe solidifies its collective belief in the reality of the nightmare. The skull becomes a kind of religious totem with extraordinary psychological power, driving the boys to abandon their desire for civilization and order and give in to their violent and savage impulses.
