It is inevitable, but perhaps we are using a different meaning for sacrifice - Most soldiers in war die in combat - Or let's say at least 30-50% of the population does - When you go to war, you are inevitably sacrificing yourself and probably going to die for the cause. I'm not talking about openly and explicitly sacrificing a bunch of people, but the fact going to armed conflicts increases the chances of dying a lot, and death of millions or thousands is necessary to win the war.
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
