Pr00ne got there before me.
It's reasonable to assume nobody with an ambition to fly fast jets, bases that on the desire to deliberately kill civilians if they made it. I certainly don't and I don't think the current men and women on the combat air frontline do, either.
Daesh intend to kill innocents - they believe to do so, forces their religious message. Fighter Pilots, Bomber Pilots and UAV Operators do not.
