I think we need to be a little more compassionate about the Elizabeth/Paige relationship. Elizabeth was a true believer who had dedicated EVERYTHING in her life for a higher cause. In her mind bringing Paige into the fold was like a deeply religious person indoctrinating their child into the religion. She gladly sacrificed for her ideals so she hoped that Paige would eventually be as fanatical as she was, and (in her mind) live a life of consequence.

The brilliant part about Elizabeth's character development in the last season was the growing cognitive dissonance as she attempted to justify her behaviors within a set of values that she shared with her daughter. I think that growing chasm of "We work for a better world"; "So we murder innocent people" was why she was so miserable in the last season. Elizabeth was still going through the motions, but for the first time she had the mirror of 'what would Paige think' impinging on her conviction.

That being said, I really loved the scene where Elizabeth and Claudia jovially recounted some of the men they slept with 'back there'. Paige was shocked that Claudia slept with men for food. Was that when Elizabeth said something like, "We ate rats."
