You seem to be surprised by hipocrisy? People will go to great lengths to justify to themselves why they're "the good guys". Having a strong dogmatic adherence to religion at worst intensifies this problem by increasing the cognitive dissonance through essentialism: "I am a good person so this thing I did can't have been that bad". This is why you'll hear people being found out to have done something for years insist "but this isn't who I am" when that's literally who they are (i.e. a person who is consistently doing those things). On the other side of the coin you have the idea that whatever you did in the past is forgiven as long as you feel really bad about having done it. Again religious predispositions can make this worse because now you don't have to repent before those affected but just before your deity (and unless you're Catholic this can even be in private rather than having to confess to another person), i.e. it doesn't matter what those you harmed think because only your deity can forgive you if it really was an evil act (and if it wasn't, those you harmed are being unreasonable if they hold a grudge). So either she decided it was moral (no matter how plausible that is) or she decided God had forgiven her or that it would be outweighed by other things she did (like being a priest).
