Explain what is meant by Golding's omniscient comment:"...the infinite cynicism of adult life. They assured Simon that everything was bad business"

Simon is standing before the pig's head on the stick. Simon feels reduced to a child against the tyranny of a sadistic head master. From this head comes the "ancient, inescapable recognition" of the human capacity for evil. Simon has always known cynicism of adult life lies on their souls just waiting to burst out in all its darkness and violence. Simon sees the dark side of human nature personified. He decides he will attempt to save the boys from their own evil as Christ tried to save mankind and was killed for it.
