I suspect that even well-meaning articles like this does society a disservice when it characterizes war as horrifying. People are not afraid of horror; people believe they can handle it. People watch horror movies. Calling war horrifying is still, in a way, glamorizing war. But even though war, the reality of war, does contain horror, war is not, I believe, on the whole, horrifying. It is instead (I suspect) boring. An oppressive and grinding kind of boring, and only punctuated with brief interludes of horror, which only contributes to its oppressiveness. I suspect that it is this aspect which destroys most people who wage war. I suspect that while some/many people do experience the horror of war (which indeed is quite horrible), most people in war do not experience much horror directly. It is instead the boredom; the oppressive, grinding, fearful boredom, which destroys most of them.
Of course, I’m only speculating; I’m not a sociologist or a psychologist.
