Nah it's not worth being discussed. One guy killing 3-15 civilians, because he "snapped" isn't news worthy. This has happened to such far far far worse extents in every war man kind has ever fought. So this guy's actions are pretty insignificant, comparatively. I mean the rape of Berlin hello? Something like 7 or every 10 women in berlin were raped by russian soldiers during the invasion. Not to mention the countless civilians murdered during that one time, in one war. It's war. Shit like this happens. It will never go away. It will continue to happen, just because of social media being able to send this information around faster doesn't mean it's any worse than what has happened in the past. They say war is hell for a reason and stupid shit like this happens. I'm not saying it's not sad and I'm not saying it's just because it's in a war time environment.
All I am saying is no it's not news worthy nor is it worth being discussed.
