Lord of the flies by Willam Golding

Lord of the flies refers to the story of a group of English boys marooned on a tropical island after their plane was shot down during a war. But the book’s exploration of the idea of human evil is to some extent based on Golding’s experience with the violence and savagery of human beings during World War II. Lord of the flies dramatizes a fundamental human struggle: the conflict between the impulse to obey rules, behave morally, and act lawfully and impulse to seek brute power  over others, act selfishly, behave in a way that will gratify one’s own desires, scorn moral rules, and indulge in violence.
The first set of impulses might be thought of as the “civilizing instinct”, which encourages people to work together toward common goal and behave peacefully; the second set of impulse might be thought of as the “barbarizing instinct”, or the instinct toward savagery, which urges people to rebel against civilization and instead seek anarchy, chaos, despotism, and violence.
The Lord of the flies shows the great struggle of the boys to rescue from the horizon. The children made a group and started doing work to attract the attention of the passing ships. They elected their own leader and started finding their way to rescue from that place and chose Ralph as their leader. Ralph elected Jack as the leader of the hunters.

Ralph, Jack and Simon set off on an expedition to explore the island. When they returned from hunting, Ralph declared that they must light a signal fire to attract the attention of passing ships. The boys began to do so; they started using the lens from Piggy’s eyeglasses to ignite dead wood. They were very innocent and do not know the importance of the work and were interested in playing more than igniting fire. So because of their insincerity towards work the fire quickly ignites the forest. And the fire becomes out of control. One of the youngest boys disappears from the group and they think that he has presumably burned to death.
All the boys started enjoying themselves without grownups except Jack and Ralph. After some time Ralph and Piggy see the ship passing by the horizon. But when ship passes signal fire burned out; it had been a hunter’s responsibility to maintain it. After that Ralph accosts Jack, but the hunter has just returned to his first hunt, and all the boys were uncontrolled and excited and start dancing. When Piggy criticizes Jack because of his insincere deed, Jack hits him.
It was really a problem to keep the single fire lit so the boys become afraid. Ralph and Jack both do not liked each other, they wanted a separate group. Jack was violent in nature so he declared himself the leader of new tribe and the group of the boys divided in two parts. They all had lost their innocence and civilization. Ralph was civilized and wanted every one to live in civilized manner but most of the other boys went into bloodlust and barbarism.
The sight of hunters chanting and dancing was baffling and distasteful to him. The first hand knowledge of the evil that existed with in all human beings was tragic for Ralph. But this knowledge also enabled him to cast down the Lord of the Flies at the end of the novel. His story ends semi-tragically although he was rescued and returned to civilization, when he saw the naval officer, he wept with the burden of his knowledge about humanity. All the children adopted barbarism and lost innocence and civilization.
They took care of the small children. Children of Lord of the Flies did a great effort to rescue from the horizon and tackled the situation very tactfully.  In the novel children tried to free themselves from the power of others by doing different kind of deeds and Jack tried to snatch away the powers of the Ralph.
