Our sense of morals are adaptive and mutable, for good and ill. I have definitely done dumb stuff without thinking in the past, I have done the wrong thing with the best and worst of intentions, I try to learn from it and become a better person.

Also, I do not have some paternal permission slip of a god who will absolve me of my wrong doings, I have to live with everything I do, good and bad, it's a pretty powerful incentive to do better and to seek professional help when needed.
