Continuing to reflect on the "vengeful hope" and drawing on Rafael Lopez-Corvo's book "Traumatic Loneliness of Children" I would like to say the following.
"Vengeful hope" is always accompanied by feelings of guilt, anxiety, depression, and masochistic punishment. This is because this type of hope does not free us from suffering and is always doomed to failure and constant repetition. It is precisely these never-ending failures that give us a sense of "hopelessness."
It should be noted that this type of false hope is unconsciously used by the traumatized state (or our psychotic or childlike part) to deceive and dominate the non-traumatized state (the normal part of our psyche).
Steiner (1982) wrote about this: "...the narcissistic part of the personality... can acquire disproportionately great power, taking over healthier parts of the personality... doing this on such a scale that it can persuade these parts to enter a perverse alliance."
Meltzer (1973) also claimed that "...the destructive part of the self presents itself in a favorable light to the suffering good part as a protector from mental pain and as a servant of its sensuality and vanity, when in reality, it is a tormentor and a torturer."
Moreover, in many cultures, there are very similar legends about mysterious musicians that vividly illustrate what our psychotic or childlike part or traumatized state is capable of.
For example, in German culture, there is a completely real story of the Pied Piper of Hamelin. According to this legend, the piper could play hypnotic music that charmed people and some animals.
The rulers of the German town of Hamelin promised to pay him a reward - as much gold as he could carry - for freeing the town from a rat invasion. He took out his magical flute and began to play. Enchanted by this magical music, the rats followed him in a procession straight into the river, where they drowned.
Afterward, when the magistrate refused to pay the mysterious musician the promised reward, on June 26, 1284, while playing his flute, he led all the city's children away and drowned them in the same river as the rats the day before.
In other words, this is not a joke or a game but a real crime that our inner child commits against our adult (normal, healthy) part, enslaving and destroying it.
I also believe that this idea is reflected by horror movie directors in plots involving children, dolls, and so on.
