Examples (quotes from the book) of why Jack in Lord of the Flies wants more boys to follow him.
Jack came to the island after being a choirmaster and "head boy" at his school, giving him some experience in exhorting power over others. His militaristic attitude led him to dominate the choir.
"Shut up," said Ralph absently. He lifted the conch. "Seems to me we ought to have a chief to decide things."
"A chief! A chief!"
"I ought to be chief," said Jack with simple arrogance, "because I'm chapter chorister and head boy. I can sing C sharp."
Jack feels that because his main interest is hunting, he should be the given ruler and make the rules for the boys. Conflict arises between Jack and Ralph. Ralph feels the conch is necessary for each boy to have their voice heard, while Jack sees the conch as rules and boundaries that try to stop him from dominating others. About Ralph, Jack says,
He'd never have got us meat.
Jack quickly learns that the fear of the beast by the boys can be used to gain their following.
"I expect the beast disguised himself."
"Perhaps […]. We'd better keep on the right side of him, anyhow. You can't tell what he might do."
The tribe considered this; and then were shaken, as if by a flow of wind. The chief saw the effect of his words and stood abruptly.
