Roger

Roger is Jack's right hand man in the same way that Piggy is Ralph's. Roger is not as important in the beginning of the book but becomes more important after the camp splits. He is a sociopath is antisocial from the beginning. He ends up killing Piggy by dropping a huge boulder on his head while on guard duty. He doesn't feel any guilt or anything after the death of Piggy or Simon. He becomes almost as much of a savage as Jack does, if not more.
