I'd argue that in the Alexandria Safe Zone, survival morality still applies. It's been made clear that the people who have duties outside the fence in the examples shown are weak. I'd counter that Rick is not a loose cannon. That his talk of killing the Dr from a survival standpoint makes more sense than exciling him as he could become very dangerous to the community's existence. He's concerned about this battered woman, and although he is attracted to her, it's a legitimate fear that her husband will kill her eventually and all he did was confront him. Actually discovering him at his house, the Dr confronted and assaulted Rick.
By virtue of turning a blind eye to this relationship, the leader Deanna Monroe (former Congress woman) is acknowleging a form of survival morality because they need him as a surgeon, they are willing to allow him to abuse her. I need to go back and review the comic to jog my memory. I remember Rick being whacked (by Michonne?) but I... I won't say any more. I'm looking forward to the Season final.
