Hate fo break it to you, but waiting to witness the downfall of WT is as pointless as waiting for Armageddon: both just are not going to happen... Your words were said by many after 1914 failed, and here we are, 100 years later with WT and 7 mil members.
Throughout mans history, there have ALWAYS been doomsday cults, some which survive the failed predictions, some that don't. Psychologists will tell you how a seemingly failed prophecy is denied by members, or claimed to have been "invisible" (sound familiar?), and their will ALWAYS be sheep to be fleeced (hint: any religion that refers to you as a sacrificial animal MAY NOT be legit).
Those waiting for justice are showing the old thought patterns of the JW's Stinking Thinking: that the righteous prevail, and the bad guy gets his come-uppance in the end. Life isnt a TV movie that predictably wraps up in 1 hour.... The freedom will begin once you let it go of such assumptions and wishes (and those with family members trapped in, I understand there's no easy escape)....
