Good point Min.
According to Watchtower theology, bad people, ranging from those who don't take a Watchtower during the last days to Judas Iscariot to Adolf Hitler all get the same treatment. An eternal dirt nap.
As a JW, Matthew 18:6 never made any sense to me:
"But if anyone causes one of these little ones who believe in me to sin, it would be better for him to have a large millstone hung around his neck and to be drowned in the depths of the sea." New Intl. Version
OK, so what if you leave the "little ones" alone, but don't joint the JWs? Or don't serve 100% whole-souled? You get the same millstone.
Death is death is death, per the WT. If fear of punishment is all that's guiding your life, there's no incentive to avoid ever-deeper pits of evil.
Glad WT theology isn't the only way of looking at the world.
