I don't think the fact that individual JWs commit horrible crime says anything against the religion itself. You can find examples like that for most, if not all religious groups. I think what speaks them is they way they handle crimes (like pedophilia) as an organization.
That's not the point. The point is that they elevate themselves above other religions; it is their anthem. They devote factories printing out truckloads of literature passing judgment on Satanic Christianity for all the terrible things they have done over the years, those demonic Trinitarians. The point is, they aren't better. We all sin. How is this different from Nazi butchery except for the degree. Give the JWs 1,800 years and see what wonderful things they have morphed into by then.
