If you were a grunt in Lord of the Rings and your opponent was the orcish horde and Gandalf was saying this to you after having demonstrated his righteous power, there might be an argument because you live in a world where anybody with a baby brain can tell the good guys from the bad guys. You were born from a mother and your opponent was carved out of mud ugly and feral. It’d suck, but it’s like fuck it, we ball.

Despite everything, this is somehow also the exact argument the op would use to justify more Ukrainians dying on mass.
