I know it's been years since I read the Zho AM, but I don't recall a lot of that. Is that from GT or CT?
It's firmly grounded in the CT materials. Tho' from a mix of vendors.
The Dark Side of the Zhodani is self-evident from the mechanics alone... A Guardian with telepathy can, reasonably, alter one person permanently per day.
Given the following facts out of the AM:Z book:
Crimes of intent are exceedingly rare in the Consulate's proles.
The proles willingly surrender after even the most heinous crimes, at least once confronted by the Guardians.
Crimes of carelessness are less frequent than in the 3I.
Crimes of insanity are usually curable.
Nobles cannot be returned to the original posting if reeducated.
Intendants who are reeducated usually return to the proletariate.
Proles who are reeducated are relocated based upon the comfort of the victim (or the family thereof) not the prole himself.
Reeducation can make one enjoy a job one doesn't enjoy.
Reeducation is not used if the individual can be easily relocated or retrained to a job they would be happier with.
Genuine disagreements exist - but common brawls are considered insanity or incited crime. And are grounds for reeducation.
Someone who is miserable or depressed may even seek out the Guardians for treatment.
If you think there's room to avoid the dark view in AM5:Z...
A few days or weeks later, the Prole returns home, much happier.
His new job is exactly what he needs and wants; a perfect
outlet for his ambitions. His successful neighbor, he now knows,
leads a shallow life without the enjoyment and fulfillment that
it should have. The world itself seems brighter and clearer. (p.14)
Sounds like they short circuited his jealousy into self-righteousness and humility. They fundamentally altered his world-view.
And note that it's days or weeks... not months nor years.
