Russell was nothing but a religious charlatan that for some thought as a special divine messenger to save the world.
Maybe he too suffering from what psychologists define as the Jesus syndrome.
The books he wrote and the literature written by the WTS to follow have the potential to sell, thats without argue.
The men who followed after him realized the potential value ( and what attention they could create toward themselves )
off of his original religious idealogical thoughts .
And thats what you have today in the WTS.
The fear cultivated by these apocalyptic end time cults will always grab the publics attention, no matter who postulates them.
