The Lord of the Flies is a pig's head on a stick, which is severed from the body of a sow which is hunted and killed by Jack and his hunters. Jack puts it on a sharpened stick, and leaves it as a gift to the beast. The parachuted man is, like the Lord of the Flies, just an innocent happening. Nothing scary. But the boy's imaginations and fears, just as Simon's did to the pig's head, make it into a beast. It's all in the mind - and the "evil" of the beast is too. What makes them scared - and what makes them behave badly - is the darkness of their own hearts
