while I have no doubt that these terrorists will go to hell because they are terrorist and they kill innocent people for no logical reason, I would like to point out that if a righteous Muslim person was killed with one of these bullets then it would not be enough to keep them from going to heaven as only the willing consumption of pig is considered a sin, having the pig unwillingly thrust upon you in no way makes that your own sin and cannot withhold your right to enter heaven.
They don't realize that beheading infidels will send them to hell.
The pig bullets is more to tell them they're damned than it is to actually damn them.
Many Americans are in the same boat... sin is sin. You don't have to be cutting people's heads off to sin. For those guilty of sin, sorry, you're not gonna make it to heaven. It's because God is who God is - "In him there is no darkness (sin) at all". God though gives us Christ, so that those who respond to the gospel, can be absolved of their sins. :)
