I would say that the WT religion is partially responsible for the split personality/life going on. My mother would make us go to meetings, out in service and assemblies. But as soon as we got home from all of this, it was as if it didn't exist. Unless of course my mom and dad got into a fight. Then it became that she was a righteous person and he wasn't.
My dad was a "worldly" person and never became a witness. I don't remember my mother ever really discussing bible things or using Jesus or god as an example for us. She left that up to the meetings to do. So she believed that the meetings and literature would educate us and she didn't have to. I don't think the religion ever made her a better person because she still is as she was..
