In the lord of the flies what do Roger, and Samneric represent in a political sense? Thanks!!!?

Roger is the torturer and "muscle" for the dictator (Jack). He carries out the dictator’s orders with violent efficiency. Samneric represent reliance and unity. They are so loyal to each other beyond any leader or dictator. They become, more or less, one person and are referred to as "Samneric". They try to be loyal to Ralph but, in the end, are too afraid and tormented to withstand Jack's violence.
