According to SparkNotes, there are two fundamental conflicts in William Golding’s “Lord of the Flies”: the predicament of being left on an island and the fight of establishing a civilised society or descending into barbarism, anarchy, and bloodshed. Golding examined the evil side of this clash in human nature through the decisions of these stranded youngsters.
Jack and Ralph exemplify the battle between civilization and savagery as two of the primary characters. At the beginning of the story, the boys select Ralph as their leader. Ralph represents rationality, order, and civilization. Jack, meantime, is more concerned with hunting and locating the beast. He eventually succeeds Ralph and establishes his own tribe. Jack leads the youngsters on bloodthirsty and violent hunts. The beast Jack and his tribe pursue is fictitious.
Simon, one of the lads, attempts to reveal that the beast resides within them, a conflict and concept that Golding created in relation to inherent human depravity. Jack and his minions reject this information and proceed to brutally murder Simon and then Piggy. By the time they are rescued, the boys have lost their innocence; in the fight with civilization, barbarism has triumphed.
