They are exemplars of evil who perform different rituals and take memories from their victims to quench the blood thirst of their insatiable souls.
But, there is someone with her deeds as the evidence of how much we can lose our humanity and the bad things humans can do with evil inside.
The Italian serial killer, Cianciulli, had brutally killed three women between 1939 and 1940.
Cianciulli who had been brought up in a religious family. She grew up under the influence of superstition, and the mystic creed she received from the diviners until her adulthood.
She told Cianciulli that the only way to save the child is some magical and mystic creed.
His elder son left for WWII in 1939 and never returned back.
Cianciulli's fear started to increase and she became afraid of losing her other child.
At this very moment, ideas, like killing people and appealing to the dead, started to come to her mind.
It's imperative that she killed three people and washed her child with the soap she made from these people and made her boy to eat the cake, again made from the remnants of these murdered people.
She kidnapped a woman living near her village and killed her with the blow of the axe to the head.
She added the sodium hydroxide, known as caustic soda among folks. Later she stirred the parts until they melted into a thick and dark mush and she poured the mixture into a septic tank
Then she grounded the dried mixture and mixed it with flour, sugar, chocolate, milk and eggs, and a bit of margarine. Then she kneaded the ingredients.
They ate the cakes with her son Guiseppe with tea; she even served these cakes to her visitors.
Their flesh was fatty and white. She melted the pieces in the oven for hours. She then added a bottle of cologne to the mixture.
And then continued to boil the mixture...
With these soaps, she washed her son first and then she gave the bars of soap to her neighbors.
Her murders were made into movies.
Cianciulli who confessed to all crimes in the investigation and was arrested immediately. She drew interest, and of course reaction, with her coldblooded confession that she gave in the court while not feeling any remorse.
