Jack manipulates most of the boys within the tribe so that he can thin the numbers of Ralph's tribe and do away with the only thing that is keeping him from supreme influence over the island. The size of Ralph's tribe is shown in the dialogue between Ralph and Piggy: ""Piggy? Are you the only one left?" "there's some littluns." "They don't count. No biguns?" "Oh- Samneric. They"re collecting wood." "Nobody else?" "Not that I know of." (Golding 155)." Throughout the boys" entire stay on the island, Jack always did all that was in his control to gain influence of the boys and become a dictator. .
Piggy is never shown a great amount of respect while on the island with the boys. In fact, throughout the novel, he is treated incredibly evil. After the split of the initial tribe, the boys on the island see Piggy as a threat. Piggy is not only one of the smartest kids on the island, but not in Jack's tribe. Jack's tribe tries to incapacitate him in order to bolster the strength of his own tribe. They do this by raiding Ralph's camp, stealing his glasses, and returning back to their camp. Jack, leading his tribe down the beach, "trotting steadily, exulting in his achievement. He was a chief now in truth; and he made stabbing motions with his spear. From his left hand dangled Piggy's broken glasses (Golding 168)." After Piggy's glasses were taken, Jack's tribe progressed to become even more evil towards the poor young man. Apparently, stealing his glasses were not enough, he had to be killed, as well. The boy's of Jack's tribe had regressed to become so evil and so savage, that they dropped a boulder on Piggy for almost no reason except that they grow tired of seeing his presence and fearing his foreboding intelligence matched up against the warlike senselessness of Jack and his tribe. Piggy was malevolently killed when, "The rock struck Piggy a glancing blow from chin to knee; the conch exploded into a thousand white fragments and ceased to exist.
