Willing victims - no one forced her to drink, and no one forced you to stay.
She's working on sobriety, she did terrible things and that makes her a terrible human being, but it won't help to make her feel guilt. She's likely repressing guilt for her own sanity. It's up to her to make amends and take responsibility for her actions when she reaches that point. Not for you to force upon her.
What step she's working on in AA is not for you to judge. She works those steps as she can, maintaining her sobriety. She does these steps for herself and her sobriety, not for you. She didn't drink for you, and she didn't quit for you.
How will it benefit her to have her defense mechanisms torn down?
