How would you support that Roger is fully responsible for Piggy's death in The Lord

of the Flies? How would you support that Roger was not Jack's pawn, but is fully responsible for Piggy's death in The Lord of the Flies? I have to argue as if I believe that Roger should receive a heavy sentence, as if he were on trial and I was a part of the jury. I am trying to convince a neutral jury member to vote for a heavy sentence, while arguing with another jury member who believes Roger deserves a light sentence because he was simply Jack's pawn, who is also trying to persuade the neutral jury member.
