We're all going to die someday so I would certainly be fine with shooting back.
If you are christian you believe mankind lives on in a happy afterlife event, nobody really dies. So no biggie if you shoot back.
If you are atheist, it's not clear why you should care about the continued existence of a species evil enough to murder your friends and family. Seeking justice for them makes more sense. At any rate it's not reasonable for an atheist to believe our species would live forever. We were going to eventually die anyway.
Religious people don't tend to be against war, historically. One general famously said "Kill them all and let God sort it out." The idea that God has knowable opinions against MAD policy seems a bit of a stretch.
People find meaning when they are alive. The person firing the missle- being alive- has as much as anyone else.
