The problem with most JWS is that they are poorly educated so when the current events are used to show mankind is living in the last days ( ie. plagues ) they eat it up like jam on toast and dont question what the JWorg leaders (GB) say.
So 30 years from now the same people at the top of the organization will implying the same fear mongering tactics.
It unfortunately works on a segment of the population.
They will become the Org's mentally brainwashed slaves as the people before them.
