This was the first time that any of the children showed any signs of rowdiness, and this aggression would only build from here.
Anthony Burgess continues on to say that, "Instead of a boy-scout camp we get young savages-painted, naked, gorging on the pig-flesh, given to torture, murder, human sacrifice to false gods." Early on in the novel, a small group of the boys, including Jack, Roger, and a few others, venture out into the wilderness on a hunting spree. They paint their faces, and set out in search for their first kill on the island. This is where they first begin to lose their innocence. From this point on, their behavior would get much worse, and their principles would decline even further.
Almost the entire group of boys have either turned into savages, or at least have begun to. The only boys that have stayed responsible are Ralph and Piggy. The cruel conduct, complete scarcity of discipline, and savage behavior have grown to such an extent that Ralph realizes that something must be done before things become even more chaotic. This further supports Burgess" statement that, "the good intentions of the few are overborne by the innate evil of the many." The struggle on the island becomes a struggle between good and evil. Ralph attempts to gather the group together, in order to address problems, keep order, and try to keep everybody thinking straight. At the same time, Jack is tormenting the other children on the island, encouraging them to rebel and making them fearful of the "beast" that inhabits the island. This encouragement only further ignites the cruelty and savagery of the boys. No matter how hard Ralph tries to keep the peace, we see that his efforts will eventually fail, as the other boys are destined to be overcome by the evil lurking inside of them. .
On the island, the boys have a fear of the "beast" that was reportedly sighted by the littluns. The beast is not actually an animal, or an actual thing on the island, for that matter.
