I was watching NG last night and after Dr. Marshall explained all the dark pictures and sayings on KC's computer it dawned on me that she may have killed Caylee just for the thrill of it. She had a perverted interested in the morbid aspect of death and torture and who is much easier to practice on than a 2 year old. At first I thought that she killed to be free and to be with TonE but she made it clear that she would not move to NYC for him. So, why would she kill for him? What are your thoughts?
