Originally posted by XanthosNZHmmm, good point but I'm not sure it completely destroys the argument. Even considering the extreme unlikelyhood of all passengers and crew of twenty planes being unrepentant Catholics, I think we can safely assume the bombers themselves would not be. It is as least possible, given they are carrying out what they see as a mission from Allah, that their own souls would depart the world even if everybody else went to Hell.
The Catholic Church doesn't know that.
EDIT: But then again they don't know much.
I'm not sure if the Bible makes references to babies who are not even Christian but imagine the administrative headaches this scenario causes which probably means that non-Catholic babies go to heaven by default so I believe this is another category of sure fire Heaven goers.
As mentioned before, if we accept an off world, possibly extra-dimentional Hell then the argument is voided anyway.
It might have been quicker if I had originally said "slightly warmer"
