> ISIL members believe they are morally justified and obligated to commit acts of terror, while US soldiers accept some loss of civilian lives to achieve the deaths of those terrorists. In all of these scenarios, the violent act is perceived by the perpetrator as virtuous.
In the case of ISIS, the author is correct. They really do believe their actions are an unqualified good. But I seriously doubt that drone pilots in US military feel the same way. They may know where a terrorist leader is, but not be able to isolate him from innocents. In other words, if they had more accurate weaponry and better information, they would harm fewer innocent people. Sadly, current bombs and armies are crude tools. In contrast, lack of ability is the only thing stopping ISIS from killing more innocent people.
I think the author is confused because the term "morality" covers everything from self-defense to religious fanaticism. There's practically nothing it can't explain.
