Set up for failure, maybe... but morality is morality, and no matter how you slice it, it helps you avoid a lot of the pitfalls that cause certain people to have a real rough go of things. Keep your principles high, but know that you're doing it because you have self-worth and respect for yourself by being a moral person, and not because you're being scared into it.
I sense a lot of guilty feelings coming from you... embrace your high standards, but try to separate them from the Cult's standards. Make them your own, and be proud.
I know exactly how you feel. I still get a chilly feeling when someone says the "F" word, I still smoke cigs (once in a while) in a sneaky way and feel guilty for doing it, and I actually still think that if I am possessed by a demon, and yell "JEHOVAH, JEHOVAH", I will automatically be rid of the demon.
*yeah, that was one thing I was told... sound familiar to anyone else?*
