That's absolutely disgusting, both your opinion, and a fact that a hypothetically "benevolent" god could allow the almsot total destruction of what is his chosen people; no wonder the Jews in Auschwitz decided that God had broken his covenant, and was no more than an evil bastard.
So, to show the depravity of mankind, God allowed 6 million Jews, and 6 million other "undesirables" to be tortured, experimented on, shot, gassed, practically wiped from the face of the earth? And mankind is the depraved one?
He allows them to die, but he allows SS Hauptsturmfuhrer Doktor Josef Mengele, Angel of Death, to live out his life in peace? He allows SS Obersturmbannfuher Adolf Eichmann to live out 20 years in peace, until Israel, not your precious God, wrought justice?
SS Obersturmfuher Franz Strangl, Kommandant of Sobibor, lived a free life until his arrest at the age of 60, and his eventual death of old age?
Or how about practically every German who manned the concentration and extermination camps, who lived free happy lives after the war, while the Jews were a pitiful, shattered people?
Does God love Nazis or something?
As a Sam Pekinpah film once said:
"God is a sadist, but probably doesn't even know it"
