Somehow my long-form answer kept getting blocked, so I'll keep this short. My point was & still is: There is NO clear cut marker to distinguish this guy as a "Grey Jedi" / "Dark Jedi" / "Light Sith" / whatever, even if that particular person calls himself/herself as such in movie, it is still an arbitrary label that could change in time with his/her subsequent actions & choices. Isn't that the whole point of moral drama between Light & Dark? As to the Valorum's snarky comment, what specific "evidence" do you require, when its all depicted in SW movies and Wookiepedia. Lol.
