Well, I don't actually think that there ever was an example of utopia at the beginning of this novel. Sure, the kids are stranded on this island that seems as if it was some kind of paradise, but very quickly, the darkness of human nature shows that this setting is more of a dystopia than a utopia. What Golding's central point is shown to be in this novel is that mankind is inherently evil and dark. When we are removed from the trappings of civilisation, such as a justice system and police, that overtly at least keep our inherent evil in check, we resort to tribal savagery and barbarism. This is a point that is underscored by using innocent boys as characters.
