All of them were crazy and sick. But there is nothing more scary then someone who is able to hurt a little boy.

Scary guy

Hot forks, cockroaches, axes; she turned out crazy. Ian was scary, but I don't think he was crazy to the core. Nanny Carrie got to that point as did Sara.

tough choice....i was between Derek and Carrie but it is soooo creepy to have someone in your life that pretends to be your brother but actually is someone that would rape you in your sleep if he had a chance, someone that stalked u and knew every move of yours...Carrie is so one crazy chick but she was a bit crazy from the beginning for me, all that hitting on Nate and stuff....Derek was actually quiet and sweet.....creepy creepy

worst tv character EVER

LOVED IT!!!!!!

Tough!

Derek still gives me nightmares though. And I rename anyone with the name Derek. It freaks me out haha

Carrie was a freak. She was kind of interesting though. I never imagined she would become obsessed with Jamie and hold Dan hostage.

Katie was a creeper too, but she wasnt as effective as Carrie or Derek. Xavier, makes me cry. It is hard to imagine he could kill 2 people (Q!!) and attack Brooke and abuse Jack. The scary part, is that people really do exist like that in the world.

ALL OF THEM WERE CREEPY. THERE SHOULD BE AN ICON FOR, ALL OF THE ABOVE.
