I still hold that an Anakin did exactly what he was destined to do. At the end of the 3rd move he destroys the Jedi. A light side exploiting dogmatic order that had, at the time, near total monopoly on force sensitivity in the galaxy. At the end of the 6th movie, he kills palpatine and dies himself. Thus ending the reign of the sith. This leaves only Luke, who never completed his training to be a true Jedi and was not above force choking people and allowing worldly attachment to sway him but is also generally good aligned.

No light, no dark, just folks. Perfectly balanced.
