They aren't analogous to real life. The Sith are much too desperate in their pursuit of power and the Jedi lobotomize parts of themselves which make them human (i.e., they are forbidden to love).

To explain further, a darkworker is quite willing to use rage as a source of power but not to the extent that they become desperate. The self-interested must guard against harming themselves. Build>Focus>Release. Being in a constant state of anger dulls the mind, destroys the body, and leads to one's own downfall. Similarly, lightworkers don't abandon the energy of rage altogether; they can't. They might transmute it into something else or move past it as quickly as they can, but without anger they would not see injustice nor would they be motivated to act. Even if they reach a point where they no longer get angry they sometimes need to provoke the anger of others so that they can guide those they wish to serve to higher levels of consciousness. (See: Steve's post about nazi eggs.)

The primary difference between -workers is that darkworkers draw their power from the will (root chakra) whereas lightworkers draw power from a sense of idealism and unity (crown chakra). Neither polarity, assuming one is on a sustainable long-term path, is absent the other end of the pole, but one's chosen alignment determines how both sides are directed and transformed.
