Being a JW you're able to ignore bad things to some level. It's the lazy way of saying, "Jehovah will deal with it soon". But when I loss my faith, the biggest gut wrench was the idea that true justice was just an illusion. That bad people in this world, and many of them, never face justice for their bad actions. I think of the man who held those three young women captive for a decade. I wonder in our world how many sick men and women are out there like him. They never have to answer to their evilness.
As a witness, I never worried too much. I was glad a just God would set all things right.The tsunami that killed hundreds of thousands of people is another mind blowing event that sadden me as a non-believer. It just showed how meaningless really we are. No more important than microbes in a Petri dish. I was told as a witness that God would intervene if the world was to face utter destruction (for example stopping a nuclear war, or diverting a planetary meteor). Anyone else was ever taught that as a JW? Yes, the religion made it easy at time not worry about such things, but focus on the really important stuff like getting those 10 hours in field service.
Facing reality is a hard thing to do. Another good reason religion and the Watchtower will be around for a long long time.
