What does the pig's head represent in Lord of the Flies?

it symbolizes evil that is in every human because no matter how rotten and old the pig head got, the remains still was left.

while it was breaking down and getting worse, it had a disgusting look and horrible smell. this symbolizes evil. something that isn't welcomed.

also when the pig head started breaking down, the author described the skull as a laughing face. evil never leaves and it also teases because it's so hard to get rid of.

i think that's what the pig head mainly was suppose to symbolize.

the evilness in every human that wil never go away once it sets in.
