Except is there really such a thing as a "Grey Jedi" ? It would be a near impossibility one would think. I mean, Jedi are those that serve the light, and Sith serve the dark, so just by being a jedi, you are inherently light. So honestly, one would think in a logical sence,
A: THose that are Jedi, are Light
B: Those that are Dark are Sith
C: Those that do both can never be fully and equaly balanced because one side will always be there to outweigh the other.
I am only thinking out of Logic here though, I mean if you have a +450 and a -450 Ok, thats grey. But as soon as you make another decision, youre 1 or more points over or under and then you are inherently good or inherently evil again.
I think that if they do make a mechanic for this they will have to rewrite some programming to make a inherently neutral choice on such matters requiring a decision to be made.
Is this not the right course of thinking?
