I think that, on some subconscious level, I still fear hell, god, Satan, etc., despite not consciously believing in any of it. Kind of like how horror films about ghosts and various monsters can be scary even though you know they're not real, but on a deeper level due to having had it engrained in me as young child. I also sometimes still get the urge to pray if I'm in a shitty situation, largely for the same reasons.
It's kind of weird, having this dissonance between my rational mind and the irrational, emotional part of me.
