I stayed away from this thread for a couple of days, quite frankly, it pissed me off...
Now that I have calmed down a bit, let me explain to you why your premise is plain wrong.
Yes, the JW do some "evil" things. It is unatural, antisocial, and ultimately extremely hurtful to people to shun them, for example. The same can be said for the blood doctrine or any number of harmful things JW do to themselves, and others.
Performing those acts no more makes them evil in of themselves as would have being a German citizen who was manipulated into joining the Nazi party in the 1930s would have been intrinsically evil. The entire German nation then was not "evil". This has been said already, but it bears repeating. Having a black and white view such as the OP is very dangerous, and ends up with bigotry and hatred all of its own. These are the very types of lessons we are supposed to learn from history, or we are doomed to repeat them.
You were a JW once. I was a JW once. At what point did you become "not evil"???
