past focus vs future focus

In the work we are doing in this month we are focusing in rewriting our past. I see the power of this however I find that this triggers to me this kind of thought loop: BECAUSE it is NOT true that 1) we are bad if we binge and we are good if we do not binge, and BECAUSE 2) we have the power to rewrite the interpretation of our actions afterwards THEN I can always binge now, no big deal, and I can find my way to feel good about it after. I am not sure this is a useful thought and it seems to me a direct implication of other concepts that should be helpful. thanks
