What comparison is implied at the end of the novel?

The dynamic of interaction between Ralph and the other boys changes dramatically in the opening scenes of the final chapter. Ralph is now an object to the other boys as he flees Jack's hunters, who seem unable to make the distinction between hunting pigs and hunting each other. As Ralph observes, the other boys on the island bear no resemblance to the English schoolboys first stranded there; they are complete savages without either moral or rational sensibilities. As they cease to exhibit the qualities that define them as civilized human beings, they no longer qualify as boys. This shift from human to animal identity is noticeable now in Ralph. No longer considered human by the other boys, he must rely on his primitive senses to escape the hunters. Because Ralph can no longer defend himself through any sense of justice or morality, he must use his animal instinct and cunning to survive.
