Most societies set up mechanisms to channel aggressive impulses into productive enterprises or projects. On the island, Jack's hunters are successful in providing meat for the group because they tap into their innate ability to commit violence. To the extent that this violence is a reasoned response to the group's needs (for example, to feed for the population), it produces positive effects and outcomes. However, when the violence becomes the motivator and the desired outcome lacks social or moral value beyond itself, as it does with the hunters, at that point the violence becomes evil, savage, and diabolical.
Violence continues to exist in modern society and is institutionalized in the military and politics. Golding develops this theme by having his characters establish a democratic assembly, which is greatly affected by the verbal violence of Jack's power-plays, and an army of hunters, which ultimately forms a small military dictatorship. The boys' assemblies are likened to both ends of the social or civil spectrum, from pre-verbal tribe gatherings to modern governmental institutions, indicating that while the forum for politics has changed over the millennia, the dynamic remains the same.
