English Social Sciences Psychology feeling of humiliation in psychotherapy

Dear colleagues,
I was wondering whether in the following context about the feeling of humiliation in psychotherapy, the term “enragement” may be interpreted as the combination between “rage” and “resentment”. I have this doubt because the author says “what one astute patient called ‘enragement’”....If “enragement” had its original meaning of “anger”, why would the author describe the patient as "astute"? Or maybe "enragement" has other nuances of meaning?
Thank you so much for your help!


Here is the passage:

Dorahy (2017) wrote that adherence to shame helps a person to avoid the realization of humiliation experience in that the perpetrator intended to wound and diminish a person. Building on that clarity is that humiliation experience is linked to a call to action, much as with anger, because humiliation holds the knowing of the enormity of the power differential between abuser and victim. If the victim risks feeling powerful, shows their proportional rage and resentment, *** what one astute patient called “enragement,” *** they are at risk of preemptive retaliation from the sadistic abuser for not masochistically accepting the abuser’s dominance. An interesting dynamic arises in this context: The failure to heed the call to action in the moment of humiliation can be experienced as shameful, and a powerful self-hatred can be generated that takes the place of the threat of retaliation.
