Either you are in "control," or you are not.
If you allow for a creature's "full facilitiy to determine how to meet the demands of overwhelming motivations," then you are giving it judegement. If you give it judegement, you have to allow for some level of determination by that creature in that judgement to fulfill the determination, which leads to endless permeatations within a population of millions...which will also lead to some degree of individuality and creativity...but which will also sow the potential seeds of rebelion.
The more you inhibit that, the less chance for creativity and the development of better technoloogies you will have, and the less chance of defeating enemies outside of your control.
The less you inhibit that, the better chance you will have of developing the better technologies, but also the better chance of having cretures under your control potentiallly break the control.
Such mind control, and such supposed "group think," and "herd," or "hive," mentalities and gestalts are thus generally two-edged swords.
