In the 1860s, 8% of asylum patients were admitted due to “religious excitement.” While that’s no longer a diagnosis, 24% of schizophrenic patients in psych wards today report having some form of religious delusion.

Religious fanatics are willing to blow up buildings and murder to please their God; anyone who doesn’t agree with them is wrong and deserves to be punished. But why does someone become a fanatic? And is it really possible to be “touched by God”?
