The path of redemption must be thoughtful and correct. Atonement doesn't mean slum prostitution and things like that. Monica's atonement, in my opinion, is, first of all, an opportunity to maintain decency where there is a temptation to humiliate OTHER people.
For example, the scene where Monica communicates with Linda and Miranda (in Linda's apartment) suggests a choice between several options to humiliate Linda and Miranda or (if Monica is decent enough) just agree to help them in the future. I'm talking about such important decisions.
Of course, the Path of Atonement should not be a way of giving up sex. It is only about the right choice in relation to the humiliation of the people around her. And this means that in future updates there should be more scenes like this, where Monica will be given the choice: to humiliate other people or act differently, not like the OLD Monica would have done.
