Upon arrival on the island, their confrontation with their situation was blunt, although they did try to appoint a chief, some disagreed with the overall result;
“and the freckles on Jack’s face disappeared under blush of mortification” pg. 30.
The truth has suddenly been put this boy into his place, who thought he is the most popular on the island, the fact now shows that he isn’t. This is a fear, a fear of interrogation, a threat of overpowering and control, and it is this fear that brings the evil to the island. Jacks need to be in control turns him and his followers into savages, and so brings the downfall of their civilisation.
After the landing of the dead parachutist, the fear of the unknown begins. They believe that the dead parachutist is “The Beast” but become too afraid to go and see if it is really a beast;
“We saw--”
“--the beast----”
“--plain!” pg. 122
Sam and Eric both claimed to have seen “The Beast”, but hadn’t confirmed anything. By finishing each others sentences here they show the fear in their voices. This fear is added to the anonymity of “The Beast” and interpritated as something to be afraid of, and to some, something that can and must be destroyed. The savagery begins.
From this savagery comes the hunting of “The Beast”. Jack demands that they should fight against “The Beast” putting the idea of an actual beast into the young boys minds, creating an even bigger fear, a fear of the unknown. The more that they think about this beast the more afraid they become, and the more afraid they become the more they think about the beast. Its a vicious cycle with destroyed the entire civilisation on the island.
The boys don’t kill “The Beast” because they fail to realise that “The Beast” is something that they created within themselves, an evil that has been portrayed from the minds of innocent boys, and twisted by the deception of false truth. The island has made the unknown into a nightmare that the boys cant fight.
