Actually, this could be an emergency if they're being taught about Hell. Are they? Is it haunting them?

I haven't seen any evidence that they're being bothered by anything.

Mostly, I just want to make it clear that, unlike a lot of other things they're learning in school, there are a lot of people who have good reasons to think the stories aren't true - to make it clear that there's a difference between "Moses led the Jews out of Egypt" and "George Washington was the first President of the United States."
