“Ralph wept for the end of innocence, the darkness of man’s heart, and the fall through the air of the true, wise friend called Piggy.” (Golding 202)
“At once the crowd surged after it, poured down the rock, leapt onto the beast, screamed struck, bit, tore. There were no words and no movements but the tearing of teeth and claws.”
Piggy represents good and Roger represents evil in killing innocent Piggy.
The boys killed Simon thinking he was the beast and at the time seemed to be the beneficial thing to do. At that point the boys lost all civil behavior in that moment of pure savagery.
Innate innocence
“The tears began to flow and sobs shook him. He gave himself up to them now for the first time on the island; great, shuddering spasms of grief that seemed to wrench his whole body. His voice rose under the black smoke before the burning wreckage of the island; and infected by that emotion, the other little boys began to shake and sob too. And in the middle of them, with filthy body, matted hair, and unwiped nose, Ralph wept for the end of innocence, the darkness of man’s heart, and the fall through the air of the true, wise friend called Piggy”. (Golding 248)
“Three small children, no older than Johnny, appeared from startlingly close at hand where they had been gorging fruit in the forest. A dark little boy, not much younger than Piggy, parted a tangle of undergrowth, walked on to the platform, and smiled cheerfully at everybody. More and more of them came. Taking their cue from the innocent Johnny, they sat down on the fallen palm trunks and waited. Ralph continued to blow short, penetrating blasts.” (Golding 1)
Even at the signs where their innocence is being lost, Ralph shows innocence by weeping and crying about what looks to him like he has lost the idea that anyone has innocence left in them
In this point in time everyone is innocent like Johnny with his cheerful smile and harmlessness.
