This is a question that plagues me constantly and to this date I have no idea if I am the only one with a much darker side. So to find out I'm asking a question to everyone here. For this thread, I want you to explore your darker side and tell me what you would do.

So the scenario is that a family member has been killed/murdered. You meet the murderer in a dark alley and no-one around to witness what you would do. What would you do?
