Lord of the Flies by William Golding


Piggy symbolizes knowledge and morality. Without Piggy to help Ralph it is very possible that Ralph may have lost sight of things and given in to the Beast. Jack, who, throughout the novel systematically removes the forces opposing him, is scornfully afraid of Piggy and eventually kills him to eliminate his moral influence on the group, which conflicts with his plan to rule with a triibalistic, survivalist moraliy.
