Art certainly has a place here. The purpose of this are isn't to look cool. The purpose of art is express and/or provoke a reaction. In this case, it's a reminder that these people exist and are suffering due to war. Most of us know war is horrible, but we don't know it the same way someone who has experienced it has. Part of the reason these pictures exist is to give us a glimpse of that understanding. And maybe if we're lucky next time around, people won't choose war.
