Everyone talks about the lake of fire, but atheists know that is useless. And most of you who AREN'T atheists should realize it, too. For example, Muslims don't have Jesus to have assured forgiveness of their sins, so the only thing they can do is to kill infidels - it is their only way to assure their "salvation" and enter into paradise. Christians are a mixed bag on this, but some pretty devout Christians during the crusades found absolution for killing non-believers. When the pulpit rhetoric makes it seem like it is a good idea to kill non-believers in your favorite sect, threats of the "lake of fire" are going to be ineffective. A typical preacher makes it clear it is the OTHER guy who is going to Hell, not devout little old you!
