I believe you can't be completely gray as a Jedi, you'll give in one way or another once in a while. But, I would be more of a gray Jedi than the Jedi Council for sure. They definitely have more rules than is necessary, and can be far too prudent in when they decide to intervene...
There is no Dark Side, nor a Light Side
There is Only the Force
I will do what I must to keep the balance
The balance is what keeps me together
There is no good without evil, but evil must not be allowed to flourish
There is passion, Yet peace
Serenity, Yet emotion...
