No tyrant comes to power on the platform of genocidal tyranny, even though such ideas may be brewing already in the recesses of his mind. Each and every one of them promises to bring back law and order, create better economic conditions, and... https://link.medium.com/Oah37vW1I9 

... restore the nation’s glory.

These empty promises -- for he has little desire and even less ability to fulfill them -- are always tied together with the thread of scapegoating of the Others, a necessary component channeling the narcissistic rage outward and increasing the society’s cohesion.

But the tyrant sows discord and division among his own peoples as well. He cannot help it: pitting people against each other satisfies his irrepressible sadistic urge and makes it easier for him to dominate and control them.

The tyrant shows up in a society that is already weakened by disorder, blind to it, and unable and/or unwilling to take corrective measures which would prevent a tyrannical takeover.

Once he and his sycophantic cabal assume power, they deepen and widen the disorder, dismantling and changing the society’s norms, institutions, and laws to fully reflect their own pathology.

(...)

We can see the tyrant’s pathology influencing every area of a society’s functioning, from politics through culture and social mores to science and technology.

What is being seen, said, and studied, and what’s ignored and silenced, depends on the tyrant’s whims, and soon enough the society itself and its ideology are structured in ways that meet his pathological needs for power and adulation.

The implementation of this ideology is usually a gradual process that is eventually reinforced by the use of violence against persistent objectors.

As freedom of speech, press, and assembly disappears and the tyrant’s destructive “reforms” take hold, an ethos of The New Man — an ideal of a human being compatible with the disordered ideology — is being forced upon the populace.

This New Man is a dehumanized caricature of a human person, usually exemplifying the tyrant’s distorted views and thus meeting his pathological needs, mainly for dominance and adulation.

He is wholly devoted to The Cause and The Leader, which in tyrannies is often one and the same, an ultimate expression of the tyrant’s narcissism, and acts in prescribed ways meant to demonstrate this devotion in his life.

Hero worship and utmost loyalty become parts of The New Man’s proscribed behavior, reinforced by new laws and norms, but also by individuals who eagerly cooperate with the authoritarian rules by spying on and denouncing their fellow citizens’ ideologically improper behavior.

Our human propensity to submit to inhumane rules established by pathological authority cannot be overestimated.

We have plenty of historical and contemporary evidence for it, as well as experimental data.
