What they paint is true to the picture. Armageddon isn't gonna be a pretty thing. So what's your beef?
You say that the organization doesn't condone its members finding glee in those dying at Armeggedon but the WTS has so many images of people dying in Armeggedon and they are some of the most elaborate pictures the organization has produced...in fact, most of the Tribulation pictures look much more detailed then the ones they make for Paradise. If the organization doesn't condone its members looking forward to the "goats" dying during Armeggedon then why make such grand images? To scare people into repenting (which is not the way to find true believers)?
