This is advocating revenge, and being pleased to see someone suffer. Imagine she had a breakdown due to stress and her life went off the rails - would you feel that was fair? How much would she have to suffer before you are satisfied?
Of course there is a subjective line here, but the things that have happened so far seem to be organic, natural, and maybe even predictable responses to the actions that that preceded. That's not revenge, that's just desserts.
