I would actually say, that my whole being is half dark. In general, my dark side only shows towards myself... in the form of weaknesses, of my sins and my negative views on myself. Or when I do think that people think or talk bad about me, even while they maybe don't even notice me.
The dark side that is an absolute negative of my normal nature would be lust and rage. As for rage, I don't like violence, however, there are situations were I guess that I would not be able to control myself at all. For example, I do hate rapists and I guess if I would meet one in person, I surely would make sure to rip his "fun zone" out, even if I have to go to jail for it...
As for lust, I do have very old-fashioned views, but at the same time, I do have very much suppressed sexual desire, which I hope that it never leads me to something that I would regret... at least in the past, I could always avoid to take use of drunken or emotionally unstable girls.
I do hope, that my weaknesses will never get the control over me.
