Well Kim likes to keep them in the panic mode....thus depending on the state....they don’t fear each other as much as they fear ‘getting caught’ by each other and turned over to the state. I will also say they can be ruthless with each other under normal conditions....well their normal anyway.
I saw an interview from some years ago, where a woman who had escaped told that even kids 10 years of age are commanded to witness public executions.
Terror is instilled in them from childhood.
