There are 2 sides to the force, the dark side and the light side. "Beware of the dark side... The dark side leads to fear. Fear leads to hate. Hate leads to suffering". Good versus Evil is a common element through most religions. The issues of good versus evil, right versus wrong permeate through the doctrines of all religions. Most religions attempt to state what is right and wrong, to establish their moral code. Sometimes religions make codes that don't reach a great consensus. Outsiders, and sometime insiders, begin to judge their religious code by something more powerful, something more innate, an innate ability to know what is right and wrong. This is the Jedi's belief, that morality, good and evil, are all axioms of the force, and that we must listen to the force so that we will know the right thing to do.
