As Jedi, we seek to cultivate harmony in the world around us.  Part of cultivating harmony is defining what is and isn't evil, and recognizing the truth of their role in the world around us.  In this episode, we don't tell you what evil is, but rather give you a tool that can help you measure the evil you experience in your sphere of influence.  As one of the pillars of Jediism, it's always good to have a solid foundation of knowledge before you tackle the obstacle of evil ahead of you.
