All he needed to do was win the war Hitler's perfect world would not at all be a bad place to be born in. Looking at the prosperous germany of 1933-1939 we can get a glimpse of a beta version of hitler's perfect world. If Hitler had won the war the utopian society could have been established. Hitler's perfect world would however be better than the beta of it from 1933-1939. Hitler's perfect world is not the same as the Holocaust. Hitler's perfect world is the end goal and the Holocaust is just the means to achieve an end. The means justify the ends. All that needs to happen was for Hitler to have reached the end goal in order to make up for whatever suffering done to achieve the end. Unfortunately Hitler did not achieve the end goal so thus far it seems not worth it. However the creation of a 4th Reich could solve this problem.

i'd like to clarify the difference between Hitler's perfect world and the 'Holocaust'

People seem to have a grave misunderstanding and seem to related national socialism in practice to national socialism in theory.
National Socialism in theory is essentially hitler's perfect world. National socialism in practice is the mass execution done in the name of eugenics
People seem to relate Hitler's perfect world to the Holohoax but people don't realize that once the perfect world is created the mass executions no longer need to be carried out.
True it may be morally repulsive with the holohoax and all but I believe the long term benefits of Hitler's perfect world will outweigh and short terms mass executions used to achieve those means.
Auschwitz will be disbanded in Hitler's perfect world once auschwitz has finished its job
Thus auschwitz was never a part of Hitler's perfect world.
Think of the world today as a crude and rough diamond ore. The mass executions auschwitz included are the refiners. Hitler's perfect world is the beautiful diamond itself. Once a diamond is perfect and refined then there no longer exists a reason to have the refiner
Thus judge the diamond not by the refiner so much as by its perfect beauty
After a few brief months when Hitler took power, Germany's economic problems went away and the country began to progress and make better of itself. True it wasn't perfect yet because of imperfections in the gene pool, but it was on its way.
