How does Jack change in Lord of the Flies from the first chapter to the last chapter including quotes?
When he is introduced in chapter one, Jack Merridew is described as "ugly," and he is clearly in control of the choir boys, who move only at his command. Piggy is intimidated by the "uniformed superiority and the offhand authority in Merridew's voice." Jack is cruel to Piggy from the start, telling him, "You're talking too much. . . . Shut up, Fatty," within moments of meeting him.
Though Jack is officious and thoroughly unpleasant from the start, he grows into a truly malevolent and sadistic individual by the book's final chapter. Sam and Eric tell Ralph that Jack, "the chief," says "we've got to . . . throw our spears like at a pig" at Ralph, who is, at this point, the hunters' quarry. Sam tells Ralph that Jack (and his henchman, Roger) is "a terror." Not long afterward, Jack tortures one of the twins into confirming that Ralph is hiding nearby. In the book's penultimate paragraph, Ralph sobs and cannot, even in his own mind, put into words the evil Jack has unleashed, thinking only "and Jack had. . . ." when he reflects on the events of the past weeks.
In the beginning of the book, Jack is just a young man who has attended a school for boys and who is stranded on an island and as insecure as the other boys. Jack demonstrates leadership qualities in the beginning when he explains to the group that they have to come up with a plan to be rescued.
However, as time passes and Jack learns that he is the more physically dominating one, he begins to enjoy a sense of power. He becomes aggressive, dangerous, and is willing to kill.
Jack, at the first official gathering of the boys, demonstrates a desire for control over the group by appointing himself chief. However, the others call for an election. Despite the election, he likes Ralph.
"Jack and Ralph smiled at each other with shy liking."
Jack likes the adventure of exploring the island, but as he becomes less socialized, he starts to change into a raw savage state of being. However, following the pig hunt with Ralph, he is still Ralph's friend.
Jack becomes more savage, controlling the others with his physical and mental dominance. Ralph becomes distant from Jack because he has not followed into Jack's level of savage behavior.
"Numberless and inexpressible frustrations combined to make his rage elemental and awe-inspiring."
Ralph and Jack separate into two groups with Jack refusing to have anything to do with Ralph's group. Jack as a leader does cruel things.
"He got angry and made us tie Wilfrid up."
"He's going to beat Wilfrid."
The twins inform Ralph that Jack is going to kill him like in a pig hunt. Jack has transformed to evil.
"The savage peered into the obscurity beneath the thicket."
