* Simon's death: This is the most tragic event and could be seen as a punishment for the boys' descent into savagery and their failure to recognize Simon's wisdom.
* Piggy's death: The deliberate killing of Piggy, the voice of reason and intelligence, is a brutal act that reflects the boys' cruelty and their rejection of logic.
* Ralph's despair: Ralph, the leader who initially tried to maintain order, ends up deeply disillusioned and heartbroken by the boys' savagery. This could be seen as a punishment for his own failure to prevent the descent into chaos.
While not a punishment in a conventional sense, the boys' descent into savagery and the destruction of their island paradise could be interpreted as a consequence of their actions, a kind of self-inflicted punishment for their choices.
If you're looking for a specific punishment, it's important to be clear about the context you're interested in. It's possible you're thinking of a different work of literature or a specific character.
