"God, from all eternity, did, by the most wise and holy counsel of his own will, freely, and unchangeably ordain whatsoever comes to pass: yet so, as thereby neither is God the author of sin, nor is violence offered to the will of the creatures; nor is the liberty or contingency of second causes taken away, but rather established." (Westminster Confession of Faith, 3:1)
Hope that helps along with my explanation of the theological distinction between Nazi holocaust Jews and futurist dispensationalist holocaust Jews.
So, you agree, then, that God does not sin, so He could not be the murderer of 6 million Jews during the Holocaust.
Why would He allow such a thing? Isn't that unjust?
