freedom and devotion

I am watching the documentary on Gloriavale Christian Community. The title is interesting, Devotion: Obedience or Betrayal. Cults interest me!

Let me start by saying that I have no idea of their theology. I did look at their website and (big tick from me) they are KJV only. And, yes, there are bad people among them. But there are bad people everywhere! I do not have the numbers (and taking the moral outrage out of it): are they, for example, statistically worse than your average sports club? Maybe the issue is expectation?!

So my first take: there is a lot of talk about freedom in the second episode, Sins of the Father, centering on mind control (taking an individuals freedom by cohesion) and brainwashing Of course, no person would willingly join! Or would they? The assumption is that people in any cult are irrational and shown the error of their ways would leave. (This, of course, simply ends in battling authorities.) Yet, what I see are people who are completely committed to their understanding of the Christian life.

So, I wonder, in complete freedom, can an individual surrender that freedom to someone else?
