Either he has the forgiveness of saint or he is totally out of touch with reality.
Seeing how he reacted to the murders, calmly and passively, I have to wonder how serious and with how much effort he sought to help his wife or take her seriously.
I know he said he sought help and it seems he did but how serious did he consider he problem?
Speaking psychologically, Andre Yates seems to me to have killed the children because it was the only way she could get through to her husband. Even then, he didn't react. He was just as passive.
I'm not Mr.Yates so I don't know his life experience, but he seems to me to be incredibly passive, even to horrific events. I'm not sure he was capable of taking his wifes illness seriously.
He was criminally neglegent in the death of his kids. THis however doesn't lessen her guilt one iota. He had an obligation to protect his wife and kids, he blew it big time.
