what is your impression of Simon? what separates him from the others?

Simon is Golding's Christ-figure meaning that he embodies the traits Christ was said to have. Simon likes all the boys including Jack. There is however always negative energy and the threat of violence. Simon can't bear this. That is why he prefers to be alone. Unlike the other boys, Simon prefers solitude and contemplation. If Simon says something, it is usually on a deep and metaphorical level. Most of them mock and jeer at him because they do not understand his message. Simon hates this bad energy.
