There you are programmed to not have a single ideosyncratic thought. You are inoculated against cruelty by beeing seeped in it, until you start to become a sadist. You are erased and replaced with a purpose within the cult. With your obedience the wrongs will be made right. You are thought that the ends justify the means. You are thought to become an expert at doublethink. You are thought to hate, and thought to express your hatred through a language of love. To speak elegantly and beautifully about kindness while simultaniously not being able to show or feel any kindness or mercy yourself.

No, they were already sadists. The purpose of the courses is to mark the matriarchy's allies for promotion and hiring.
