Grey.
At the core I'm a Jedi, since I'm into asceticism, control of emotions, meditation, calm, etc.
But I despise how the Jedi forbid everything with their shitty morality, like no killing (their enemies), no screwing, avoiding too much knowledge into dark secrets of the force, etc.
It's just showing their weakness. In this regard the Sith are actually right 99% of the time and much more enlightened.
Problem with the Sith is that they let their impulses rule them, and eventually that becomes a weakness because they do foolish things.
So I would be a Jedi, but probably kicked out and hunted down by Jedi soon after I become a master.
