Evil in the world is represented by savageness, ignorance, and animal instincts, in contrast to the good influences of a mindful civilization. People created civilized society, but savageness will always exist, because it is part of human nature. Far from the decent communities, savageness always works to overcome good. William Golding and Fernando Meirelles present these ideas in their works, the novel Lord of the Flies and the film City of God. They tell the stories of two places with no rational legal authorities, where savageness is way of life. In these stories, Piggy and Rocket are similar in that they become outsiders in their communities because of their mindfulness

This is the main reason that Piggy is an outsider in his community of children. His cultivated and intelligent mind does not fit in the savagery and primal instincts ruling the life of the boys in the desert island. The first signs of Piggy's isolation can be observed in the first chapter of the novel. Piggy cannot stop talking about the airplane crash, his aunty, his social problems at school, and about the things that need to be done: "We got to find the others. We got to do something" (14). These are all reasonable commentaries that a rational person would emit. The other boy, Ralph however, considers this to be annoying so, "ignoring Piggy's ill-omened talk, he dreamed pleasantly" (15). Piggy cannot see this, because his intelligent mind cannot understand that kind of ignorance. He continues his fight against the savageness on the island, looking for a way to put some order in it, while at the same time insolating himself from the group. Piggy becomes a prominent figure in establishing the two main symbols of civilization and order on the island. First he finds the conch, and immediately puts it to use: "We can use this to call the others. Have a meeting" (16). The conch becomes a symbol of power and order, because the boys use it to call meetings. Moreover, the one who holds the conch has the right to speak and to be heard. The second symbol of civilization is the signal fire that the boys created in order
