The moment humans brought nuclear armaments into the world was also the moment that we severed ourselves from our humanity. We are still living in the shadows of metaphorical guns to our heads. This escalation of madness has led us down a very dark path, and for that reason, I'm out.
Wars have always been brutal and involved murdering/raping citizens. Don't act like nuclear power made a change in morals. Only thing that changed is the scale. The darkness has always been there.
