My idea here is that the Ahrimanic impulse - which is evil in its cold, rational, systematic manifestation - has over the past couple of centuries consumed the more traditional Luciferic ('devilish') evil of short-termist personal lust, pleasure and torment. And is now being-consumed, in his turn, by 'Sorath'.
The archetypal Ahrimanic evil is epitomised by a manipulative bureaucrat who presides over a state or corporate PSYOPS/prison/death machine; while Luciferic evil would be characterised by proximate evil: for example those who personally beat, rape and torture helpless prisoners.
The final turning-point of the Ahrimanic consumption of Lucifer was when the Luciferic revival of the 1960s ('sex & drugs & rock-n-roll') was captured by the state bureaucracy - leading to a pervasive and intrusive system of monitoring and control for political correctness.
Modern leaders are primarily Ahrimanic - and often anonymous/ hidden/ personally-timid; while old-style leaders were often Luciferic gangsters and pirates who cultivated a reputation for recklessness and the enjoyment of inflicting cruelty. Luciferic evil now operates at a low-level in The System - among the mooks, minions and henchmen; while the ruling architects of evil have an Ahrimanic nature.
The Luciferic values were condensed and operationalised into systemic and materialist form; their spontaneity and pleasure were drained-away. 'Free Love' and open-ended promiscuity became compulsory sensitivity-training, and the threat of harrasment prosecutions. Spontaneity ("Turn-on, Tune-in, Drop-out") was incrementaly transformed into a world of proliferating committees, laws, guidelines and procedures; checklists, forms and feedback...
But from about 2000; there was a further move towards the purest, most absolutely negative form of evil - which could be named Sorathic (adapting this from Rudolf Steiner's identification of Sorath as the most extremely evil of beings).
Sorthic evil is neither about pleasure nor about control; it tends towards the purely destructive.
If Luciferic evil is motivated by short-teremist pleasure; while Ahrimanic evil is motivated by God-denial, spiritual blindness and reductionism towards a meaningless world of mechanical procedures; then the Sorathic impulse is driven by negative impulses - primarily fear, resentment and hatred.
Sorathic evil will therefore tend to destroy both the lustful pleasures of Lucuferic evil, and the complex functional bureaucracies of Ahrimanic evil.
This is the Sorathic world we inhabit in 2020.
A world in which the Luciferic lusts of sex/ drugs and the rock-and-roll lifestyle are forbidden and punished; and also a world in which the global system is being disabled and destroyed - even as its Ahrimanic architects have successfully accomplished a silent global coup, and are trying to perfect it into the grandiose schemes of The Great Reset/ Agenda 2030.
In 2020 we observe all modern institutions, corporations and every kind of bureaucracy as rapidly declining in efficiency and effectiveness - under pressure from an ever-increasing culture of fear, victimology, entitlement and resentment.
Sorath divides Mankind into more-and-more, smaller-and-smaller, self-identified victim groups; each resentful-of and pitted-against each other. The aim is eventually for each person to feel alone, consumed by feelings of thwarted entitlement, and hatred of the world; and living in permanent fear of a whole world of other people, each of whom resents and hates the solo-victim just as he hates them.
And then - eventually - Sorath's intent is that everyone, without exception, should die in fear and despair.
Thus we see that Sorath takes Luciferic and Ahrimanic and pits the one against the other, to weaken and destroy both. Whatever gives pleasure is thwarted. Whatever has been created, and is complex or functional, is reduced to chaos.
Chaos is indeed the key term. Ultimately, Sorath is driven by resentment directed against God and all of His works; and resentment of Man as a loving creating-being and all of his works. Sorath wants to reduce creation back to a primal state of chaos.
And then - when all else has been destroyed - to destroy himself as a act of spite against the God who created him.
Such is Sorath's fantasy.
Note: JRR Tolkien depicted Sorath in his Silmarillion legendarium under the name of Morgoth.
