Unprompted

Honestly, I think if Mary had admitted she knew damn well what she was doing, and was understandably guilty about that, I'd have more sympathy for her. Altruism and self-sacrifice are fine to talk about, but actually being willing to give up your life for someone else—which is probably what refusing to rat people out to the bad guys would have come to, for her—is a pretty tall order. Not everyone is that brave, and being forced into a position where she had to choose between her own life and the lives of the people around her was a miserable and unfair position the villains are responsible for putting her in.
