Not good at all, MOF such unprofessional behaviour strikes me as out of character for him. I really doubt that any self-respecting operative would go off half-cocked and try to kill that best source of information available; a more realistic scenario would be for Curtis to kill Assad after the terrorists are stopped.
I don't endorse Curtis' actions. I merely state that, unlike the racist neighbor, he has some justification for wanting to kill Assad. His men were slaughtered like pigs by Assad's people.
