I do think that there are issues with his own children. I think he loves them dearly and would never do anything intentionally to harm them, but I do agree with you Rachb that some of the things he does may affect them in later life and that he isn't capable of seeing that.
It is a difficult one. I really hope that he doesn't lose his children as a result of this documentary, but I also feel that he needs help and advice from a responsible friend/adult about how what he is doing is percieved and the effects it could have on them.
