Yeah Lizzie needed killin. She was a little freak even before her mom died back at the prison. I need to go rewatch that episode, but I think her mother knew that she had problems, and was a serial killer in training. Me and a guy at work decided the best punishment for Lizzie would have been to tie her to her sister and wait for little sister to wake up and eat her. After some pain and torture and the realization of what she did sinks in, then cap them both in the head. I have to admit though that Carol did a good job. Some people just need killin. I sure wouldn't have ever been able to sleep around her again.
