Yes I agree that there is something very wrong with Karla. Even if she was battered by her husband she would not agree to go along with his depravity. He obviously influenced her and I think he was the instigator but there is something lacking in Karla's emphathy and she doesn't take responsibility for her actions. Two seriously damaged and dysfunctional people came together. I don't believe that a person with normal feelings would partake in the kidnap and sickening abuse that happened in this case. She should be in prison for the rest of her life and should never have got out to have children of her own. What is wrong with the justice system to let someone like this walk?
This reminds me of Rosemary and Fred West and also a case that happened where I live David and Catherine Birnie.
