Jack starts the novel off as a prestigious choir boy, who cares for law and order. It infuriates him, when he is not chosen as chief, as he enforces authority back home and wants to do so here.
I'm a chapter chorister and head boy. I can sing C sharp.
Jack has taken up the role as a hunter, who craves blood and the death of a pig. He has neglected all previous responsibilities and morals to kill. This is the first sign of savagery Jack shows. The zoomorphism is taking over and Jack experiences more primitive behaviour, such as the quote "bent double" at the start of chapter 3.
seductive, maddening - the promise of meat
I thought I might kill.
Jack has lost previous emotions and has inhabited savage behaviour. Jack is lost to civilisation and has become savage and his no longer feels the wrong doing of his actions. Chapter 4 is when the readers can start to see a big separation between the hunters and Ralph.
Jack hid, liberated from shame and self-consciousness
Jack is lashing out the littluns to show his superiority and to gain power. He is using the idea of the beast to frighten them but also by showing he is not afraid of the imaginary creature. Jack is acting like a bully to show others that civilisation is not the best way forward.
you useless lot of cry-babies
Jack is gaining power from his hunters and followers as they continue to obey him. The use of a capital letter at the start of the noun Chief implies that this is Jack's new name and title. It also takes away power from Ralph and civilisation as he is no longer chief so has little power. The hunters look up to Jack as a leader and Jack is respected by the other savages.
The Chief has spoken
You're acting like a crowd of kids.
The tricolon of insults Ralph throws at Jack is a surprise to the reader. It is the first time in the book that another character calls a person a pig and a beast. These insults are describing Jack as the Lord of the Flies and as the beast, whilst Jack is simply savage. Ralph is so horrified at his behaviour is has no choice but to threaten him. A page later Piggy dies as a consequence of them both offending savagery, Jack and the hunters. Throughout the book Piggy symbolises intelligence and has an adult outlook on the boys situation but when he claims that savage behaviour is a character trait of children, it creates a sense of irony, as the boys are only child and Piggy does not think of himself as a child. Jack is portrayed as a savage beast at the end of Golding's novel as he and Roger kill Piggy and destroy the conch, the symbol of civilisation.
You're a beast and a swine and a bloody, bloody thief!
