Thanks a lot for the insight and the elaboration, well clarified.
Just one note: "The acting out of the emotion can either be proportional to the amount of abuse, or disproportionate, in this last case causing more damage than the initial abuse." - The damage also depends on external factors, for example if the abuser is much more powerful than us, it might be less damaging to act out with disproportionally low anger than to act our with proportional anger. Would you agree?
What you are talking about is the negation of acting out. It is the refrain from acting out the behavior due to the perception of the opponent being more powerful. So you can have not acting out (which is this case that you are mention), or acting out as one does in self defense (proportional), or in case of disproportionally like in domestic violence.
