If you were able to get rid of Eric before sacrificing Alice or chose to let Kira remain as the sacrifice, (1) will hold trueNow this I remember very well. Alice tells Max when asked, that nothing happened.
This can be taken two ways...
1: Nothing happened.
2: Something did happen, but Alice refuses to acknowledge it just like with Max in the Bathroom before Kira's arrival
If you chose to sacrifice Alice for Eric to stop fucking Kira, (2) will hold true. There's an image were Alice gets out of her room after her "session" with Eric having the look of great shame in her face (I felt sorry for her). Alice is no stranger to sex and had felt close to Eric from the start. For her to wear a shamed face after getting out of the room, you'd assume or wonder what kind of abuses she got from Eric.
In my opinion choosing to sacrifice Alice to save Kira is stupid. Kira, with her profession, a sex veteran, and her willingness to be sacrificed to protect the family, is the most logical choice. I understand the part of satisfying audience kinks though hence the choice.
