It's strategic overkill - but it's how the little creeps think... Don't you feel there's something inherently evil about an organization with that much money that purposely uses techniques that cause their own people to die? Do they want to hear the screams? Their "man" was burned - did they want a "close up"? These are sick perverts. Something is going on that we really don't understand.
It's like the story of the street bombing where two innocent children were put in a car to be blown up - and Americans noticed it because the town got quiet while all the subhuman monsters were quiet - watching and waiting for the young children to die a horrible death.
I agree. There is something so evil at the heart of Islam that it's hard for us to comprehend it. There's no way we can understand a "religion" that boasts about its love for death and regards every human being as simply fodder for its onward devouring march.
