The irony of the plane crashing to start the story, the environment of an unknown island and many other cruel acts work in the The work as a whole because it really sets up the major plot of the story. Cruelty will bring out the worst in people and this phrase holds true when it comes to Jack. The killing of the pig and the obsession with bloodlust drive Jack to savagery and reveal that he is not morally strong. The violence also shows that Jack is manipulative as he uses the fear of the beast to gain power. While cruelty transforms Jack, Ralph remains morally strong and represents civilization throughout the novel. Cruelty proves that Ralph's character is very intelligent because he is able to think deeply. The cruelty also reveals how morally strong he is and how he will not succumb to savagery like the majority of boys do. Lord of the Flies by William Golding, simply proves that the cruelty of our savage and bestial instincts will take over without the order, rule and conduct that civilized societies must respect.
