I have always told my children that their actions are their own. As parents we teach our children right from wrong, its up to them to do what's right. I do think there are learned behaviors. I also believe, from their interview, that he learned, it's okay as long as you have a reason. I hope they didn't somehow put the idea in his head. Not saying that they meant to, but who knows where the idea came from. It all started with an idea. But at the end of the day, CW and CW alone was responsible for the death of his wife and 3 children. The facts won't change just because his family is in denial.
