The Watchtower Society has the appearance of being decent, but it doesn't go all the way down to the core. It's like a chocolate covered cow pie. Sure it tastes sweet at first, but eventually you move past the candy coating to the pungent poopie center.
If you take a peripheral look at their literature, you'd think that they were an extremely moral and decent religion, but that's just for show as the very center, the leaders of the religion don't have to follow these same rules. They have convinced themselves that they are the closest thing to God on the planet and so they don't have to worry about responsibility, the truth, admitting faults, or any of the other values they insist from their followers.
So, in summary, a lot of Jehovah's Witnesses, the rank and file, are sweet like chocolate. Unfortunately, they surround the cow pie center of the Governing Body.
