Jack is considered the most suited to leadership in Lord of the Flies.
Jack is the leader of the choir, and continues to direct the choir as the boys are on the island. He tells them what to do and when to do it. However, Jack does bring the boys, acting as one strange creature, to Ralph when Ralph blows the conch.
When the boys decide to vote on a leader, they choose Ralph.
None of the boys could have found good reason for this; what intelligence had been shown was traceable to Piggy while the most obvious leader was Jack. (ch 1)
Ralph is chosen because of his “stillness” and his possession of the conch, and because he was the first person to blow the conch and gather the boys.
The fact that Ralph is chosen as leader instead of Jack is a constant source of conflict. Jack does not make a good follower. Ralph also allows him to continue as leader of the hunters, the former choir. This does not appease Jack though. He continually threatens Ralph’s authority, until finally he breaks away.
As a leader, Jack is violent and volatile. He beats boys for no reason, and encourages his boys to paint faces and bodies and conduct violent dances. Eventually, they murder both Simon and Piggy.
