Isolation does weird things to the mind, one of which distorts reflected appraisal, other parts where reflected appraisal is denied in communications are even more impactful. It induces a involuntary hypnotic states which varies in intensity by exposure.

The tortured takes on mannerisms of the torturer, and when denied communication, or only distorted reflected apprsail long enough their entire being unravels, and you have psychotic break or disassociate completely. The psychotic break is a semi-lucid state where planning is capable. To make an apt comparison, an active shooter might fall into this latter category. Years of investigations into what causes these people to do what they did, and the powers that be can only say with certainty that these people were bullied, but no clear cause can be found.

Coercion is a dangerous thing.

You can corroborate what I've said with the literature in the books I mentioned, or with isolation studies where the studies had to be cancelled early for the safety of the study participants. There is a lot of research out there.

Destroying someone's identity, their personality, what makes them them, is true evil, and these structures are how you do it which is why its so important to recognize the problem, few do.

Your comparison is apples to oranges. It is not asking someone a opinion, its silencing them entirely by force, where they are disadvantaged when they don't answer. There is a very big distinction between the two.
