I've done some research into the JWs and have a few friends who're JWs, and also have a friend whose left the JW organisation.
JWs do believe in Satan, but do not believe in a Hell; they think this is a 'scare tactic' created by the Catholic church. And who-ever mentioned the 144,000 going to heaven is correct; and the rest of the 'worthy' will live for ever here on earth; Paradise Earth to be exact.
JWs are Creationists, and they're looking forward to the end of the World, where most of us will be zapped and they will live in Paradise with their resurrected. I bet a fair few of them get excited when earthquakes and the like happen.
But with regards the resurrections, there's a few problems regarding this, for example, say a JW is widowed and she re-marries. What happens to the resurrected husband in Paradise Earth? Does he sleep in the room next door to his wife and her next husband?
The main thing the JWs receive culty critisism for is when they try to leave the organisation, or do not adhere to standards set by elders (which some can appear to behave like little Hitlers from the stories I hear).
Anyway, the JWs practise something called shunning, where members of a congregation shun an individual for some reason. This has the abilities to break up families, for example where parents must shun their son or daughter, because they wish to leave the faith. Suicides and broken homes have stemmed from shunning. Also the members are discouraged from mixing with 'worldly people' i.e. you and me, and are encouraged to not to go looking for answers from outside the religion.
Leaving the religion can be a traumatic experience! If anyone is thinking of being a JW I would suggest you get as much information both good and bad before you make your decision. There's many websites set up by ex JW members who could advise you better than I.
They don't celebrate Christmas either!
