Mississippi Trial Chapter 2 pages 17-25

I'm going to go with Grandpa being worse. Sure. R.C is sadistic, but he has lived a life of abuse at the hands of his alcoholic father. He has some redeeming traits like being protective of Naomi. Naomi is the one person that he does not tease or make trouble for, although Naomi worries about how much trouble he is causing other people. Grandpa is racist to the point that he can morally justify it. He knows he is guilty but hides behind lies and inuendo. He is perfectly happy to let someone else go to jail for his heinous crime.
