I just hate the fact Obi-Wan said "I would have given up the jedi order, had you given the word" then a season later he refuses and taunts maul into butchering her.
Plot hole much?
He was obviously talking about the old days when once upon a time Obiwan was still a Padawan under Qui Gon. Since then, Obi has become a Jedi Master and has matured. Winning the Clone Wars is top priority, he couldn't just walk away from something like that.
On a side note, Obiwan as a Padawan was always ready to leave the Jedi Order for one reason or another. In a lot of ways Anakin is more mature in that regard, which is kinda funny given their personalities.
