In terms of the motive of why she would rape a child she would adore, we already know that many sexual assaults/rapes are about gaining power and control.
A victim of abuse often feels powerless. So she might have entered into a childcare situation subconsciously looking for a way to have power ( I know a few teachers that appear to have entered the profession as a way to be powerful and in control). So if NR was suddenly out of her power/control (suspension from work, NR showing affection towards another worker, etc) she found the most brutal, primal way to regain power over NR.
By the way, none of this IMO, whether or not it's true, is an excuse for CR's actions. I tell my students every single day, the majority of whom suffer physical abuse and neglect, that the only person responsible for their behavior is THEM and that no matter how angry or hurt they are, they do NOT have the right to hurt someone else.
