If the thoughts which this tale provokes can be put under light of expanding the frame from family to its local surroundings, to the more distant realms, which reflect back on every family life, I would call it a success.

I will make myself unpopular in saying that holding the tension and letting the reader feel and also re-member (reactivate) what he or she as an individual might have experienced within childhood (identifying with the children at the table) would better be ended. In the sense of "closing the Gestalt", like, for example within therapy.

People are sensitive beings, their very imagination and ability to reactivate personal trauma from experiences might then linger and stay within them.
While cliff hangers - leaving the reader or viewer in suspense - may be selling well, I would say that the human being prefers a "happy end", which in this particular case, could have just been to release the tension. So, not "happy", but at least closed in some other way.

Do we lack overall in literature and films the very descriptions and characterizations of the tyrant, the evil and such? I don't think so. Often we leave a story with seeing nothing but victims, where it could actually be told further.

Where can the victim be seen and their experiences be reframed to get a different look at them, and come up with the realization that what evil happened to us as children, prepared the later adults for an early warning system to recognize tyranny on higher up hierarchies?

Having said this, I also would back away again, for we are all adults and what may not be said here in the comments, might nevertheless be thought of.
