To really know Reinhard Heydrich, you can't imagine the 'typical' villain. He wasn't consumed by rage, nor did he have a wild ideology like most of the other leaders in the Nazi regime did (for example, Hitler & Himmler). While the other leaders computed their thoughts with emotion, Heydrich computed his using reason (and left emotion out of it). The emotion stopped the flow of information. He didn't use hatred for his output, he used efficiency.
He viewed people, not as human beings, but rather as a ledger entry. He viewed them as a 'problem of a population'. He viewed them only as entries in a ledger and was only concerned about them to the extent that they could be sorted or categorized and when necessary removed as a population from the face of the earth. He did not view murder of anybody as something to be done out of rage, he viewed it as a procedure - a line item of a bureaucratic work flow.
Because of this reason, he made those members of the Nazi old guard that were fanatics & sadists uncomfortable, as he could not be predicted as a fanatic and manipulated as a sadist, which made him more difficult to understand. As the so-called 'Nazi Man with the Iron Heart', Heydrich approached power like he did, fencing or the violin, he approached it precisely, timed, and with discipline. No theatrics, no hesitation.
As the next stage of the machine of Nazism, Heydrich saw the future of Nazism in the use of technology to be the new world order. In this sense, it could be said that he was the 'architect' of the new world order. As a result, his goal was to create a state with unrestricted access to technology that would give the Nazis total control over everything and everyone. That is, to sort and categorize every aspect of humanity into two categories, 'good' or 'evil', and then to eliminate as 'evil', everything that fits into the evil category.
