"At the very worst, in a nutshell, people in that religion have been convinced that God will destroy those who are not ‘in the truth’. "
Yes, that's true. But they long for that day - all of them. And become very desensitized(sp?) to human suffering due to it. See a baby hungry? God will fix it "Real Soon Now". See a homeless person? God will fix it "Real Soon Now". See 5,000+ people die in a collapsing pile of ruble? God will fix it "Real Soon Now" (not to mention they were going to die anyway "Real Soon Now").
This doesn't even begin to address the vast # of JWs who 'joke' about 'inheriting' the mansion they come across in FS, or get excited at events like the WTC. Or make a big deal about the 13-14-whatever JWs that died in the WTC - ignoring the other 5,000. Or 'using' the WTC (or other similar events) in examples like they did at one assembly where the 'sister' who was weak and took a job at the WTC instead of pioneering "and now she's dead" ... don't get me started ...
