Yes, in no way more or less brutal than the Cartels. As ruthless and horrific as it is, and as Col. Kurt's puts it in Apocalypse Now it's "brilliant and effective." We hail from western culture and a lineage of free thought and action, a culture where justice and mercy are idealized. Culturally their (ISIS, Cartels, Terrorists. etc..) actions are beyond our imaginations and abilities. But their horrific actions give us impetus and a rational for why they need to be stopped. Much like the realization that the Nazis were tyrants and had to be confronted. So, for every evil actor set on the stage there will be a cop, soldier, good guy who's dream it is to cut the assholes down.
