Ralph
Ralph is chosen by all the other kids as the leader at the start of "The Lord of the Flies." He is an athletic, smart, and likable main character. In the story, he symbolizes order and civilized leadership. He focuses on working and increasing the chance of being rescued, instead of playing and having fun. As the other kids give into their savage instinct, Ralph tries to stay morally strong. But he eventually gives into his, and the other kids, savage ways. He goes to Jake's feast and takes part in killing Simon. The kids are eventually rescued but Ralph cries at the end of the story because he has learned of the evil in every human and has to live with that burden on his shoulders.
Piggy
Piggy is Ralph's right-hand man or his "Lieutenant", as he's called in the story. Piggy is a very smart young boy. Even though the other kids make fun of him, he becomes the leaders right-hand man and helps the group of boys in a lot of ways. He first starts a signal fire when his thick glasses. But due to the group of boys neglect and little respect of the fire ends up burning down a large section of the island. He also creates sundial for the group of boys to tell time. Piggy symbolize order and leadership like Ralph. But Piggy represents more than just that, he represents rationality and the necessities of logical thinking and intelligence.
Jack
Jack is introduced as the leader of the choirboys, but loses the election as the leader to Ralph. Right away I could tell that Jack desired control and power over the other boys, especially Ralph. Jack is a strong willed, savage, violent, and egomaniac young man. But Jack and his followers are told by Ralph to explore the island. Jack discovers a wild pig and hesitates when he has the chance to kill it. Disappointed in himself and worried about what the other boys think, he devotes himself to finding and killing the pig. This is when the savage in the boys start to show. Jack paints his face like a savage and wants to kill. The new ferocious Jack appeal to the all the boys besides, Ralph, Piggy, and Simon who try to stay civilized. Jacks new group or tribe he has established adopts and encourages a violent and barbaric lifestyle. This savage lifestyle leads to the murders of Simon and Piggy, but Jack doesn't care and is just happy to have control.
Simon
Simon is smaller kid who is simple, not in an intellectually, but morally and simple with his beliefs. He is very connected to nature and is quite spiritual. Most of the other boys abandon there morals as soon a civilization and punishments are out of the picture, but Simon is different. Simon realizes that there is and was a beast on the island but not the same one that the other boys thought there was. Simon discovered that the beast was the boys savage ways and thoughts that each of the boys had on the island. This is showing the reader that, even with young boys, most humans resort to savagery actions before civilized ones. But not everyone does this, Simon kept his morals when everyone was not because he knew it was the right thing to do. Simon's morals and his fight against evil makes him a symbol to Jesus. But Simon also symbolizes the good in society, and also the good in everyone that just need to get past all the evil. In the end, Simon's disgusting murder by the other boy's shows the power and the large amount of evil in this world.
