Add YoursJack Merridew
The leader of a boys' choir, Jack exemplifies militarism as it borders on authoritarianism. He is cruel and sadistic, preoccupied with hunting and killing pigs. His sadism intensifies throughout the novel, and he eventually turns cruelly on the other boys. Jack feigns an interest in the rules of order established on the island, but only if they allow him to inflict punishment. Jack represents anarchy. His rejection of Ralph's imposed order--and the bloody results of this act--indicate the danger inherent in an anarchic system based only on self-interest.
Roger
One of the hunters and the guard at the castle rock fortress, Roger is Jack's equal in cruelty. Even before the hunters devolve into savagery, Roger is boorish and crude, kicking down sand castles and throwing sand at others. After the other boys lose all idea of civilization, it is Roger who murders Piggy.
Maurice
During the hunters' "Kill the pig" chant, Maurice, who is one of Jack's hunters, pretends to be a pig while the others pretend to slaughter him. When the hunters kill a pig, Jack smears blood on Maurice's face. Maurice represents the mindless masses.
