How did Hitler become Hitler?

I know my question seems very broad or even obvious but what I am trying to figure out is how Hitler convinced a nation that genocide was for the greater good? I know their was fear mixed into it but was there a social stigma already in place that made it possible for Nazi's to follow suit so easily? How does a single man convince a nation that genocide is not a big deal? How did Hitler do it?

Nazi education is often very lackluster because it focuses too much on Germany itself and too little on the actual mechanics behind Nazi ideology and fascism which can come about in pretty much any shape or form and in any country.

Probably the best description comes from the NSDAP member Carl Schmitt who describes how fascism works.

According to Schmitt, fascism works by creating order through an eternal enemy. So establishing a strong identity by fabricating an ever-present other. The fascist state must be in a constant state of war with the other. This war cannot ever be a metaphorical 'war of minds' or something but a very real, concrete war that speaks to the primitive fears of the people. Creating an atmosphere of constant fear for survival among the people is essential for the fascist state. This fear manifests in hate towards the other and cruelties being inflicted on the other which, in turn, provokes fears and violent reactions by the other which then provokes even more cruel reactions. Therefore a fascist state will always culminate in genocide and war and can never, ever be peaceful. Peace being the one constant normative goal of all political philosophy, fascism fails miserably in this most important aspect. And so it can never work.
What the other was for the nazis you already guessed: The Jews. Today's nazis like to create more abstract ideas such as 'deep state' or other conspiracy theories but the mechanics work the same and we can see today that the fear is getting more and more real and guided towards actual people. But not only nazis can be fascist. Something that nobody really seems to understand is that ISIS and other islamic extremist groups are, for all intents and purposes, also fascist. Here the other are the kuffar. They capitalize on fear of the other by comitting atrocities which provokes violent reactions to justify more atrocities.

Additionally, the notion that Hitler was the only man responsible, putting everyone under some kind of diabolical spell is wrong. There were a lot of people who made Hitler what he was.
