If you buy into his theories then its not irrational. I hate to break it to you, but most of his opponents believed the same stuff with some differences. Lord Keynes was the president of the British Eugenics society. Churchill as a huge supporter of Eugenics, forced sterilization, and lets not forget his views on the colonial people.

Pretty sure the British didn't stuff people in ovens, regardless of their other manifold sins, nor aimed to remove 30+ million people from Eastern Europe and enslave the remainder to form their own colonial Empire.
I don't think I need to go through France and the Jews do I.
France also elected Leon Blum in 1936, and their crimes happened under Nazi domination - admittedly of the own accord of the far-right government, but a government that was formed because of the Nazis, not because of internal political movements.
Let's be blunt, the Nazi's just massively ratcheted up what was already taken as truth and being acted upon amongst the Wallies.
There is a big difference between systematic racism and eugenics programs and aiming to kill scores of millions of people and convert Eastern Europe into a slave state.
That's one reason I think its important to actually understand these people, they weren't that different from us. Things like the Milligram experiment tell us that we could easily have done the things the Nazi's did if you just change the circumstances around.

The Milligram experiment had a lot of flaws, the researcher who did it twisted the results.
They weren't in some separate category you can just write off as having nothing to do with us and no logical motivations, that they were inhuman killing machines for no reason. It wouldn't even be correct to say they were uncaring monsters. Hitler won two Iron Crosses for bravery. One was from diving into no mans land to try and save a comrade.
Bravery is the most democratic of human virtues. The worst rapists, murderers, villains, torturers, can all be brave. Bravery from genocidal maniacs does not much impress me.
t's not correct to say they killed for the sake of killing. They had goals that necessitated a lot of killing. Those goals had some sort of positive nature in their mind (a better Germany). We can say the goals are evil themselves or the actions taken to achieve those goals are evil, but in their minds they were doing a "good thing" via a logical path based on the initial assumptions they had (which we can also consider wrong and/or evil, but I think we need to acknowledge hour widespread such views were at the time).
Hitler's long term goal was a state of endless war for the purification of the German race. That rather sounds like the goal of killing for the sake of killing.
Should they achieve those goals the killing may stop. Even if they liked conflict itself is that much different from today in the US (where we come up with at least one new war a decade on more specious terms then the Germans faced). Stalin and Mao were pretty bloodthirsty too, eventually both settled down so to speak. I'm not saying you wouldn't get an Anglo-American war scenario, but you could just as easily get what happened with Russia and China OTL. For one, I wold expect a lot of those people, including Hitler, would have been dead eventually no matter what happened, just like Mao and Stalin eventually died.
I'm sure the slaves on their plantations in Eastern Europe would be overjoyed at the new, friendly Nazis.
It's dangerous to write these people off as just insane or metaphysically evil because if so we have zero to learn from the incident. After all, none of us considers ourselves insane or metaphysically evil, so that would never happen here, right. They were regular people (or at least within the bell curve of what we'd call sane, they didn't have actually clinical chemical imbalances*). Regular people, even people who are sometimes brave and selfless, can do terrible things and believe terrible things if you put them through the right circumstances.
Of course we have stuff to learn from them as regarding human nature - they weren't a different species separate in their emotions and impulses - but the Nazis legitimately were a step above anybody else in their cruelty and horror.
*I do think the levels of drug use both by the Nazi's and many rank and file soldiers led to many of the worst atrocities especially once the war got started, and that would be a kind of chemical imbalance of the mind but not a natural one.
War crimes by the troops has always happened throughout history. It doesn't take drugs to do it.

It disgusts me how much of a free pass communism gets with some people despite causing the deaths of untold millions on a reasoning that was about as equally indefensible as "they are untermenschen".
Maybe because it didn't plan to genocide all of Eastern Europe, wipe out the Jews, launched wars of aggression against the vast majority of European countries, and in the short period where it was actively involve in murder managed to kill over ten million people and scores of millions of war dead. The communists were awful, but they pale in comparison to what the Nazis were actively planning.
