Eclectic: to some people, desecration of a corpse is offensive for a variety of reasons. Your attempt at moral equivalence misses the point.
Whomever died, and however he died, he's dead. The civil war in Syria is terrible enough.
To then take the trouble to descerate the corpse for ideological purpose, or for some act of showmanship, is a different sort of horror, with different motivations than fighting in a war.
