This irrational, group-oriented collectivist paradigm is what fosters externally guided actions. When orders are received from those individuals commonly accepted as the "authorities" of "the group", and as long as the orders fit nominally within the collective values projected by "the group", it is perfectly "normal" from a collectivist's point of view to follow those orders – even when they are orders to aggress against someone, whether someone inside or outside of the group. Additionally, those who are trapped in the collectivist trance (virtually all human beings presently, with only very few exceptions), are themselves vulnerable to group-sanctioned aggression, for their loyalty is to the group.
To anyone who has completely broken free of the collectivist paradigm, it is clear that the collectivist paradigm – the mindset that relates to others by group association and submits to group dynamics – is the very bedrock of the State. The collectivist paradigm compels the individual to subordinate his mind, his very power to think and to discern, and thus his choices and actions, to the tenets of the collective. Yet, those tenets evolve to reflect the desires of a minority of individuals; namely, the "administrators", a.k.a. central planners, that the mutually held "group" fantasy spawns out of necessity – precisely because there is no actual "group entity", with its own über-mind, capable of administering itself. Thus, the illusory "collective" functions as a disguise for the master-slave relationship between a minority of dominant individuals, and a majority of submissive individuals.
This is why groups, especially political and religious groups, inevitably become dominated by the brightest narcissistic sociopaths participating in "the group": Only a sociopath would have any desire to rule, bully, or dictate to others. The group model of human association, supported by the collectivist paradigm, is what makes it possible for these sociopaths (who are very much a minority) to rise to positions of dominance from which to disingenuously impose their sick fantasies upon their fellow human beings. The bigger the group, the bigger the pool that these sociopaths arise from, ultimately producing more extreme tyrants.
