A decade ago, when I first started Kurayami as a character I had just finished playing through both of the KOTOR games(not first playthrough, more like thirteenth or more). How much he bounced around between Sith and Jedi would have given a pinball vertigo. Eventually I began to realize that neither of those allowed the full extent of writing a Force sensitive character, and started to read through Kreia's dialogue trees and responses to certain actions and dialogue options. That is what led to me developing him as a Grey/Neutral FU who strives to learn as much as he can about the Force as a whole, seeing it as neither light nor dark, but instead as a myriad of facets. To him Light and Dark, Jedi and Sith, are nothing but labels used to villify/justify one's actions as greater than those of another, the Force itself has no such dichotomy, that rests solely within the wielder. In his mind it is all about balance, if you cause harm, do equal good and vice versa. I have found this to be much more helpful in writing a character that reacts naturally to a situation than a Jedi or a Sith might.
