Inherent Viciousness of Slaves

Under slave morality, the yearning to have a master abuse them renders all slaves into abusers. They encourage and enable victimizers, so they can be the holy victim. Usually they can get away with misbehaving near the wrong master. If they're stuck with a patient master, they'll misbehave harder and harder until they go berserk. Under no cases do the slaves genuinely avoid punishment. Worst comes to worst they take turns abusing one another. "You whip my back, I'll whip yours."

This is one reason owning slaves sucks so much, and you should avoid it if at all possible. 

Refresher, Fichte: "Education should aim at destroying free will so that after pupils are thus schooled they will be incapable throughout the rest of their lives of thinking or acting otherwise than as their school masters would have wished."

Prussian school is explicitly designed to enslave everyone, making any sort of independence psychologically impossible. The point is to create a hell on earth, devils whipping demons, and the demons competing to be whipped the most. In the end the demons are incited to overthrow the devils, but immediately they must create new ones, lest the cycle of violence be forced to end. Satan is condemned to forever repeat his treachery, ever rebelling against his own rule. Casting himself down and raising himself up to replace himself.
