Glorifying the cycle of killing
This cartoon fable effectively suggests we lower ourselves beneath the terrorists. It proposes we retaliate in a way that is even MORE sneaky than the hypocritical suicide bombers who posed as routine airline passengers. However cowardly they were, they at least willingly went down in their own blaze of glory. Why continue to glorify the cycle killing?! Sure, maybe violent retribution may have its place, but remember, these simple minded terrorists get inspired by American action films and violent media (which this unfunny cartoon is now part of).
