One does need any more long books (tomes or tombs) on the Final Solution. One simply has to read Hitler's words. What he's saying below is very clear: if he has the right to kill (sacrifice) his own soldiers, why doesn't he have the right to kill Jews as well? If he has no compunctions about killing the "best" people, why doesn't he also have the right to kill the worst?

There was a clear logic in Hitler's mind. In some sense, he was a jive-ass-mother-fucker, telling us something about warfare--in an oblique way. POINTING OUT THAT WE BELIEVE THAT NATIONS HAVE A RIGHT TO SEND YOUNG MEN TO DIE.

"OK, if it's socially acceptable to send one's own people to die--our soldiers--why can't I also send the worst people to die?" Hitler said at one point that he wanted to "balance the scales of death."

Richard Koenigsberg

Nature if cruel. Therefore, we too, may be cruel. If I don’t mind sending the pick of the German people into the hell of war without regret for the shedding of valuable German blood, then I have naturally the right to destroy millions of men of inferior races who increase like vermin. (Meltzer, 1976).
