Vidiot, what you say makes sense, yet I read something today that makes me challenge it slightly. Because I’ve been reading about Mormons (who I would consider to be on the spectrum of high control groups) who interestingly reject the concepts of “depravity” and “original sin”. I’ll quote what I read:
“Mormonism rejects the notion that man’s condition is best described as ‘depravity’. Nowhere within Mormon theology is its optimism concerning man’s natural condition more clearly apparent than in this denial of the Christian doctrine of original sin... in contrast with the orthodox Christian notion that the fall resulted in a condition of human depravity, the Mormon view asserts that the fall was a necessary condition for man to realise his ultimate potential... to the Mormon the fall is a fall upward rather than downward.” Jerald and Sandra Tanner, The Changing World of Mormonism (1981), 192-193.
So in contrast with JWs, strict Calvinists, and many other Christians, I think Mormons would say that humans are fundamentally good in nature rather than bad. Yet they still manage to be a high control group. Brahma Kumaris also seem to teach that the human soul is fundamentally good, yet they also display controlling characteristics.
I also found this article about Jains to be quite disturbing.

Having said all that, I mostly agree with the point you make, that controlling religions tend to emphasise bad human nature, whereas more liberal groups tend to emphasise the good in human nature: the Quakers, with their “something of the divine in everyone”, and Unitarians with their belief in the basic dignity of all people, are cases in point.
