Yes there’s a difference between the treatment of the jews by the Germans to any other genocide and inhuman treatment in the world. It was the industrialisation and the sheer scale. The death of all jews was the goal not an unintended but acceptable collateral. And the Nazis did their level best to make killing as efficient cost and labour wise as possible.

That to this day is unprecedented to this day. Even saying this is coming dangerously close to relevation of the holocaust which is a crime in Germany - and for good reason. The Nazis for this fact alone were not demonized, a lot of them acted so mind-boggenly inhuman that demon is the most fitting word for them.
