Well, even if this ends up being the case, if during the time she's been a Sharran she has done evil things, she's still guilty of having done those things, isn't she? Innocent people suffered because of her actions. Why should the slate be wiped clean? I just don't accept the idea that if you do evil things but then later on express remorse and "repent," that's all it takes for you to be absolved of your evil actions.
I agree with you, the slate should not be wiped clean. I like redemption stories, but in order to be redeemed, a person has to earn it. They have to turn from their evil ways and actually do good in the world.
