Killing little girls is not something any man should do, ever. I'm not talking about collateral damage in war. I'm talking about lining them up, putting bullets in their heads and dropping them in mass graves. Only a sub-human would be willing to do that. It's just plain wrong. Aligning oneself with the 'lesser' evil is still evil.
When you acquire a few decades of experience about sub-humans, then you might have something to say on the topic which could be worth listening to. Not earlier.
