The aim was to subliminally indoctrinate a person over many years, so that by the time they came of age and were ready to be recruited, a cult's beliefs and rituals would not appear inappropriate, dangerous or even fatal.
This was especially true for people who were designated to become sacrifices to spirit deities, of which there were many in Scarfolk. One particularly insatiable deity was Rupert, a Robot Penguin Lord, who consumed so many sacrifices between 1970 and 1975 that he developed diabetes and put on so much weight that he had to completely replace his wardrobe.
