Christians, as well as believers in other religions, have long been overlapped with people of mental illnesses, and convicted criminals. Most of the victims of mental illness profess to being very religious, having seen angels, or think they are "Jesus Christ."
There's a similar phenomenon in the prison system.A majority of U.S. prisoners (about 98-99%) are religious-affiliated. Whether these conversions happened before or after their imprisonment is debatable, but the truth still stands: A very small minority of prisoners aren't religious.
This basically brings me to say that most of society's crazies or degenerates are religious and or spiritual, at least in affiliation.
