Yes, I think killing each other is somehow tied into the 72 Virigin thingie, and who's Caliph has the biggest......... turban or something.
The important thing though, the key to it all, is the application of massive quantities of Trinitrotoluene and/or Pentaerythrite Tetranitrate to your fellow believers in the goodness, mercy and love of Allah.
Nothing says "The Peace of Allah be upon you!" like a carful of Trinitrotoluene!
