" fear is the main tool of domination used by all psychopaths"
I was scared to death of the minister at the church my best friend went to as a child. He always spoke about the wrath of God and how we should fear God. That's how he thought people should live their lives in order to become good christians. I know he's not the only minster who preached that way. Yet, I don't think he was a psychopath.
Bad logic.
"If you are a psychopath, then you use fear to manipulate people."
is not the same as
"If you use fear to manipulate people, then you are a psychopath."
You still will find many a preacher using fear to try and bring people to Christ. It does not work long term. One of the errors of the Christian church today is the belief in everlasting hell fire (no wonder people think of God as cruel). No instance can be found in the Bible supporting everlasting burning fire that torments people. If you examine the original languages, Hell is termed everlasting, but everlasting in the context that it is permanent death, not death (or sleep) that is talked about as the first death.
I wish preachers would examine things themselves a little bit.
