"Self-righteous, irresponsible, and fond of violence - excellent material for a terrorist puppet-master. Personally I'd put Jamal's head on a pike as a warning to the others. That worked very well for the Turks for a very long time."
I agree bigtime, cut them in half, feed half to the pigs, put the rest of the carcass on a cross (they'd love that) with the head on a pike. Douse the carcass with pig fat and pig blood and tie a necklace around the head with pig feet on a string!
Then perhaps some song can be raised,
"Hail to the Religion of Piss, its warts and scurvy clans. Bring 'em all to their desired ends and toss in their Imams."
