A lot of these super crazy religious people are Calvinists. There are different levels of Calvinism, but as you go higher it means that there is no free will. All humans are "on rails" essentially, just completing the design of God. Even to the point that all humans who exist have been pre-sorted into going to heaven or hell before they are even born. Individual actions don't matter, and if you're going to hell there's nothing you can do to change it. It's the will of God.
