The problem, I think, is the skill Dubbie kids develop in leading two lives.
Almost all do it to some extent or the other, even if it's down to just keeping their masturbation a secret, rather than admitting it as they should and receieving guidance and council. Obviously with most, having wordly friends, not appearing like a freak at school, taking part in unapproved activities secretly rather than not at all, and keeping one's innermost thought secret are additonal behaviours that are developed.
'Wordly' kids obviously might have to develop the same skills. For a Dubbie kid it's almost essential for sanity.
Obviously, most kids keep their maturbation a secret, but doing so isn't 'wrong' to them.
The abilty to conceal wrong thus develops from an early age. JW kids are trained to lie, as they have to to survive.
This development of an ability to deceive one's parents so as to be able to attain 'normal' goals in life can carry on as a habit, even outside the cult.
Some xJW's find it easy to carry on deceiving people to achieve their goals. Even after being removed from an environment where deception to attain normality is almost compulsory, this habit of deception can be carried over to where one uses it to attain whatever a goal might be, rather than just attaining some semblance of normality. The goal becomes the focus, regardless of means.
I doubt if I'm the only xJW with a criminal record. I was stupid, and commited fraud to finance my study at University. I thought I had no other way of escaping, as everything I had went to my x-wife and kids, and the fact it was wrong was not important enough to me at the time to stop me doing it. My goal was more important than my means.
I gave myself up after three years and did Community Service, as I didn't want it hanging over me, and had recovered enough of a moral framework to realise I had done something that I actually strongly disapproved of.
