I won't quote all of post 45. But I think jediphile hit what Kreia was about perfectly. Kreia never accepts being Sith or Jedi as anything more than a title to allow her to teach. Does she manipulate the Exile? Yes. But I think it's clear, in that moment before the masters, that she is done using them, and makes her case clearly.
It also makes sense with the cut content where she attempts to break and then take the "Lost Jedi" of the Exile as her own. It was her anger at the council's impotence that drove her to the Sith, I think. And it's their continued refusal to deal with the truth when the Exile finds them that mandates their death.
