How often do you question whether to acknowledge a voice you hear in your head? What about those gut feelings that defy your own logic? Maybe you assume listening to invisible signs suggests you should also be seeing little green men? Would that be so odd? The latter aside, would you not gain a lot from being more honest with yourself? Consider this;

1) What if conscience is a misunderstanding?  Ask yourself what your life would be like if you stopped creating a sense of guilt in situations that originally imply no punishment or retribution.  As past, present and future don't exist, mistakes don't involve penance. Otherwise, you could easily say it came before the incident that supposedly justified it.

2) What if human beings are intrinsically good?  Ask yourself if you accept your mind has free will.  As you have choices about how to consider your thoughts and actions, you can assume they are positive or negative. You can assume they simply are.  You set the point of reference and rationalize what will appease your ego.  You may also transcend it.

3) What if your views on cause and effect are misguided?  Ask yourself to reflect on karma and how you believe it influences your life.  As multiple existences are simultaneous and open-ended, your past is still unfolding in ways you don't recollect. Unless you choose to step outside the conditioning of your linear consciousness, you won't perceive differently.  You won't realize lives you have lived are not you, while they still are of you.
