Bill Burr had a bit about getting up to heaven and at first thinking it's awesome. Hey, I just have to wait for my friends to die and we can all hang out together. Then after awhile, you start wondering where your friends are and after few decades or a century it finally starts to sink in that those guys didn't make it. How much would it suck to try to enjoy heaven while all your friends are burning in hell.
I think that's what some of these people are afraid of. This guy's family loved him, but thanks to their sick, twisted worldview, all of this crap was justified cause otherwise, he's going to hell for eternity and they won't get to be with their son in the afterlife. I'm glad my family belonged to one of the sane church's that received Chick tracts rather than handed them out.
For those of you outside of America who may not know what a Chick tract is, it's these comics from Jack Chick that you'll find laying around in various places by crazy people. If they're extremely hateful bigots, they might place them in the pews of Catholic churches or Jewish temples. Here's one on homosexuals. http://www.chick.com/reading/tracts/0273/0273_01.asp
