War is loving stupid and killing anyone regardless of the reason is disgusting.
While I won't go so far as to say war is a necessity, it certainly won't be going away anytime soon. I wouldn't even compare wartime killing to murder, seeing as while a murderer is killing another person for their own reasons, a soldier is just following orders. However
Killing is loving sweet.
Go kill every person you see.
This is just plain stupid. There's a difference between killing an enemy and just killing everything.
As for Shinji, I'm glad to see his commitment to join the Army isn't wavered by something like this.
