You always know the difference between right and wrong, and no matter how much you might wish otherwise, a distracting little voice in the back of your mind scolds you when you go for "wrong." Anytime you act in a manner which could be considered "wrong," "bad," "evil," or frowned upon, you must make a Self-Control + Focus check of 15 or perform the task at −2 penalty. If, as a player, you lack a well-developed conscience, the GM can fill you in, but "wrong" typically has to do with breaking major laws: killing, stealing, fraud, telling lies, breaking and entering, and abuse of others, animals, or drugs.
