Well, you are assuming all this charecters existed which outside of the bible as little evidence for any of them.
Even the bible only mentions a few of them by name.
I don't know ask john smith and his followers the Morman guy witht he gold tablets in america.
Those who followed Muhammad.
The people in the Waco compound.
There are people who really beleive something and will die for it.
Next the "Documents" of their deaths are in the books thats are not canon. Some of them are crazy.
