Virgins

How can one man kill innocent people for his religious beliefs? For the promise of a large number of virgins waiting for him in the afterlife? Speaking of this belief I saw a humorous play on it, I believe on Family Guy. They showed an extremist blow up some people then when he got to heaven he did have virgins waiting for him, just not the type he expected. He found a bunch of pimple faced computer geeks playing Dungeons and Dragons. That was hilarious. But back to the topic. Where does a group get off killing fellow members of their society for religion? That is not appropriate and will never be accepted. What point does it serve? They are just killing some many innocent people. If you want to kill yourself then go ahead but don't take away that choice from someone else. I hate suicide bombers because they take away that choice. How can you justify killing all those people to yourself. I will never understand.
