At the end of the novel, Lord of the Flies, who really is Lord of the Flies?

In Lord of the Flies, Jack and his
hunters cruelly kill a sow, a pig, and then cut the head off and hang it on a stick. The
flies swarm around the head. Jack and his boys sacrifice the head to what they call the
beast. The head becomes the Lord of the Flies.

In an
interpretation of the pig's head on a stick, it becomes representative of the beast that
is inside Jack and his savage hunters. Jack becomes a cruel savage. He slits the pig's
neck and slings blood on the boys who laugh
hysterically:

Jack begins to rub the blood on his hands onto
Maurice, and then they notice Roger withdraw his spear. They become hysterical because
he had pinned the sow by driving the spear through its anus. They reenact the slaughter
until they grow tired.

Simon
sees the pig's head on the stick. He is given a message by the pig. It is as if the head
is talking to Simon:

The message that is given to Simon by the Lord of
the Flies exemplifies this. The Beast (evil) is in each one. Previously Simon had stated
the same thing, though he was roundly
ignored.

When Simon runs to
share what he has seen as the beast, the dead parachutist hanging in a tree, he
encounters a deadly hunting-dance frenzy. The boys are dancing and reenacting the
killing of the pig. Caught up in a hunting frenzy, when Simon comes out of the forest,
the boys assume he is the beast and they begin to tear and bite at him until they kill
him.

Truly, the beast is within the boys. Jack is a
representation of the Lord of the Flies. He is in authority over his choir members. He
has no trouble pulling out "steaming colored guts" from the pig they kill unmercifully.
Jack himself has become savage. He is a good representation of the Lord of the Flies as
the pig's guts and blood become a part of him. No doubt, the flies swarm Jack in a
symbolic
form.
