Hello to you,

a fitting setting to portray a human being, a will-breaker. Nevertheless, this successful snapshot of the existence of a family who are all afraid of their mother's tyranny cannot be complete.

If one expands the frame and adapts the family dynamics to it, it can be assumed that a despotic person in a family will be fought and rejected by those involved. The strategic means people use to avoid direct confrontation and otherwise disobey calls for creativity on the part of those involved. I think there is a certain dynamic in many families that, when an adult has become too set on his or her tyrannical rule, something is done to counter it. The children's strategies, for example, can vary greatly. While one child may silently and fearfully comply, another child may cut off the bully through innocence and kindness by emotionally turning to the very aspects of a tyrannical parent that are still intact.

And even these roles can change situationally. Where the fearful child obeys in one situation, it may not feel its fearfulness in another and spontaneously react positively without thinking. In the same way, it may spontaneously react angrily and petulantly without thinking.
Since the family as a whole always witnesses everyone's behaviour and reaction, and this dynamic, whether consciously or not, reveals all aspects of human character, the negative is experienced along with the positive.

The portrait of a through and through, everlasting tyrant with exclusively cruel intentions, does not hold up in such absolutes within families. Except where one cannot get out of the vileness of his existence, eventually becoming the ultimate victim. By killing out of hatred, for example, or by being killed himself. Less drastically, such a person may end up alone. Without family, without friends, without love.
Where a tyrant is nevertheless not abandoned or abandons himself, and someone remains with him or her, he or she will have contributed in some way to avoiding this tragic fate.

The boundary between victim and perpetrator is characterised by the fact that it becomes blurred. A positive reframing in relation to children who learned to exist around the whims of a bully are precisely those who later as adults recognise the germination of tyranny on the other levels such as society and politics much earlier, because they have sharpened their sensory perception and sensitivity and in this respect have become better judges of human nature vis-à-vis any form of oppression than those who always existed on the sunny side of life (although this too is only to be seen in relative terms). These often traumatised children are then adults who emerge as early warning signs. Far too often, however, they are called "troublemakers", "worriers", etc.

As a constructive criticism or challenge to you, I would say that the elaboration of contradictory aspects in the character design of the individuals lends a multi-dimensionality to a story. The very aspect of empathising with the bully on other levels, seeing his motives and being unsure yourself whether to hate or love this person is the great art of creating stories.

Greetings to you :)
