Analysis
The triadic structure builds from the abstract ("end of innocence") to the universal ("darkness of man's heart") to the painfully personal ("called Piggy"), summarising the novel's entire message. "The darkness of man's heart" makes explicit Golding's thesis that evil is innate within all humans, not external. The elegiac tone of "wept" confirms that the boys' experience has destroyed their childhood forever.

Exam Tip
