momental. As a core 6 and Extraverted Perceiver, I can attest that one of our biggest struggles is to rely on our selves to make our own decisions about what is good for us and right for us. NJs are wonderful people, but they can also be very influential, especially NFJs, and unless you are considering going to a professional counselor, I would discourage the idea of enlisting a stranger to help you figure out something internal - because they are likely to sway you to their own view of things, even if they don't mean to. Core 6s have trouble trusting their thoughts - surprising to hear, for an N-dom! But the more we look outside ourselves for answers, the further away from the real answers we will become. The more we look inside, and inside alone, the closer we will get - even if we feel unstable, unsure, and afraid. As ENP 6s, we have to learn to trust our internal value systems to make good choices and stop looking to external theories to "solve ourselves". Funny, isn't it? What I have learned from the Enneagram is that I need to not make the Enneagram the answer. :]
I think you are already on the right path, @The Great One, and simply experiencing cognitive dissonance. Your superego (essentially your learned conscience with heavy parental influence) is telling you that you're going to be punished for certain actions while your Ti tells you that you want to take things logically, case by case. And then to top it all off, Fe is probably tapping you on the shoulder to remind you that karma is more than just a religious belief - it's an actual phenomenon (ie, if you're bad to someone else, it creates negativity that may well eventually be carried back to you). You are in the middle of a hard struggle, and you know that. Be strong and stay true to yourself! You know what makes sense to you - trust your Ti. It's your "good parent" function, and it's there to help you. If you ever feel like you're getting too logic-heavy, you can engage Fe via pleasant interpersonal reactions - it's your "relief" function, and should help ease your stress - which should help balance you out. Personally, I find meditation and time alone in nature helpful for clearing my head of outside opinions and focusing on my independent, internal, personal thoughts.
FWIW, I definitely believe you are ENTP. Your mind-structure is very different than mine and other ENFPs I have discussed with. :]
