From Robert Louis Stevenson's Jekyll/Hyde, Romans 7:14-17, Two Face, Supertones song "In Between", Or Johnny Cash's version of The Beast In Me. I think that everyone has heard of the same idea. Depending on your world view it may not be sin but it is at least not "you" or the version of you that you strive to be.
I tried to imagine somewhere between Two Face and Jekyll and Hyde with a Belief in Romans 7.

This took me forever... I need to learn how to take portraits and especially self portraits. It was added trouble that it was without a remote and with an added complications of using lights (which I know nothing about) and then editing two poorly planned shots into one image+photoshoping it to death. All told I think it took me about 9-10 hours on it.
It was fun
