The only reason it (probably) hasn’t been done is because nobody is willing to go that far + the past experiments were limited to the medical capabilities of the time.

When has it been done? Give me an example. What did the subjects endure? Worse than what we know about MKUltra? Was their suffering amplified through mind altering substances? If they haven't, then it hasn't been done.

If it has been done, I'm surprised I haven't heard about it.
