The freedom offered to him by the island allows Jack to express the darker sides of his personality. Without adults as an authority, he begins to lose his fear of being punished for improper actions and behavior. This freedom, along with his mean and arrogant personality, make it possible for him to quickly degenerate into a savage. He puts on paint, first to camouflage himself from the pigs, but later he uses it hide himself from the possible consequences his actions might bring. Through hunting, Jack loses his fear of blood and of killing living animals. He reaches a point where he actually enjoys hunting a prey with his spear. As Ralph becomes confused, Jack begins to think himself as chief. The boys realizing that Jack is strong and evil, give in easily to the freedom of Jack's savagery. Jack gradually becomes more violent and the rules and proper behavior by which he was brought up are forgotten. The freedom given to him unveils his true self letting out his darker characteristics. .
Piggy is an educated boy rejected by the kids of his age group on account of his appearance. On the contrast to Jack, Piggy is short, very overweight, wears glasses, and is asthmatic. It is his isolation from the savage boys that allows him to remain unchanged throughout his experiences on the island. Unlike Jack who gets attention easily, Piggy is ignored by the boys. "We don't want you." said Jack flatly. (24).
He learns of the hatred being brought out of the boys. Although he is easily intimidated by the other boys, especially by Jack, he did not lack the self-confidence to protest or speak out against the indignities from the boys as the shy Simon did. .
"He was intimidated by this uniformed superiority and the offhand authority in Merridew's voice. He shrank to the other side of Ralph and busied himself in his glasses."(21).
This self-confidence differed from that of Jack because it did not come from the authority and power Jack had grown accustomed to.
