I will NEVER like Carol for the simple fact that she allowed her abusive husband to sexually abuse and possibly rape her daughter. She did NOTHING to stop him. And then she screamed and cried when they found Sophia dead. If she cared so much why didn't she do something when she was alive? What kind of mother does that? Carol is and always will be weak. Right now she thinks that she is so tough, but in reality she's just gone crazy.
She even admitted to it in s2 when she was praying. "Lord, is this my punishment for doing nothing while my husband lusted after his own daughter?"
