Not meant to be snarky, but why does any abusive system attract and foster dysfunctional types and their behaviors? The same parallels can be seen in any abusive relationship. Understanding this, would answer your question.
Take a few steps back and look at what happens with abused women, (JW has quite a few of these), subjects of totalitarian regimes, salespeople for MLMs, (again, many times also JW), and you begin to see a pattern. Abused people have low self esteem and believe their abusers are there for their own good. It starts a positive feedback loop, (vicious cycle), that is difficult to break from.
