The paranoia fuel is part on what makes the concept of Hell so potent, by playing on the fear of what comes after death. Just because you transgressed this one small rule, you are condemned into eternal punishment. And you don't even know when you will die or be able to repent.
This idea is also why many atheists, skeptics, and less dogmatic believers write off such an idea as preposterous.
There's also the notion that since it seems since God is all knowing, he can actually see the future, including if you are going to Hell or Heaven. Meaning all those stuff about how you have to choose your own destiny is all lies. Happy living, everyone.
This is the idea behind the Calvinist and Islamic concept of predestination. Meaning that God has decreed your final depository beforehand and you can do absolutely nothing for it.
Which increases the paranoia and Tear Jerker. You can be the nicest, sweetest person in your town. Construct and run no-kill shelters for abandoned pets, adopt disabled orphans, fund foster homes, donate to the poor and needy, etc, but you'll go to Hell anyway because God has seen to it before you were born.
It should be noted that, in the Christianity-based religions at least, that God does not determine where you are going in the afterlife from birth. He merely knows what's going to happen, as one's own actions determine their place after death. Though in Calvinism and several traditions do state he does so, based on several biblical quotes that imply that.
Gnosticism laughs at the two examples above and makes it more horrifying. Your entire existence is pretty much to be food for an evil lion-headed god and his angels, unless you adhere to exceedingly ascetic rituals and ways of life that may or may not allow you to escape from physical reality. And sometimes, the archons don't feel like waiting for you to die.
And how can you tell if someone's under Archon control? They act like The Fundamentalist. How many people do you know who act that way?
