Quote from Lord of the Flies Page 75

"Kill the pig. Cut her throat. Bash her in."
-Lord of the Flies Page 75
This chant is the first clue that the boys are becoming more and more savage. Island life is de-conditioning them from what they were taught back home in London. The boys repeat this chant in a ritual they perform to symbolize the hunt. They appear to worship the act of hunting and killing pigs. They are more interested in the pursuit of meat that they will eventually forget of being rescued and their lives in the civilized world.

Lord of the Flies Pages 40-60

The boys begin to realize that living on this island is not going to be very fun. Ralph and Simon construct shelters for everyone, while Jack tries to kill his first pig. All the other boys go and play in the ocean or sleep. Ralph begins to become frustrated because all of the other boys won't work. His leadership skills seem to be slipping because he cannot seem to get the boys to do what he wants. Simon is becoming more and more withdrawn. This is a sharp contrast to what at first he came across as. He seemed at first very outgoing, but this may have just been a cover for something that he is hiding. Jack seems to be becoming obsessed with sticking and killing a pig. He only talks of killing pigs and every thought he has includes pigs in some way. This obsession may have started because of the boredom of living on the island. The pigs offer a hobby that help focus him away from other things.
