In the microcosm of society demonstrated on the island, Piggy represents intelligence and civilisation. He mimics the actions of an adult on occasions such as suggesting that the boys take a register. Piggy's death is a direct consequence to the boy's savagery and is a turning point at which they decend into complete chaos. It shows how all rational thought has deteriorated. As piggy is crushed by the Boulder released by roger, he clings onto the conch, showing his loyalty to the system first created when the boys arrived on the island. However the shell shatters in his hands, destroying the symbol of law and order that once kept the boys in harmony.
