What is the conflict between Ralph and Jack in Lord of the Flies?

In the book Lord of the Flies  Ralph
is appointed leader by the boys whn they land on the island.  Jack felt that he should
have been the leader because he is the leader of the boy's choir.  It is their first
conflict.

Later Jack becomes more savage.  He desires to be
the hunter and make a kill.  As he exerts his power through his ability to hunt and
kill, the other boys are drawn to him.  He maintains his power through his savage
behaviors and bullying.  He is essentially the evil of
man.

Ralph tries to maintain dignity and compassion despite
the trials of living on the island.  He slowly loses control of the boys as their
leader.  Ralph is the good side of mankind and he wants to continue to have order and
civilized behavior.
