It works especially well when the torturers know when the victim is not telling the truth.
Now would it work on Clyntahn is another question.
There is no question about the moral problems of torture but there are times that it is necessary.
Claiming that "torture never works" ignores the moral question of "what do you do when if you don't torture the info out, innocent people will die".
The argument for torture is often a classic case of prioritising the tactical over the strategic. Leaving aside the moral question, torture can be a short-term, tactical gain. Which is why soldiers are trained to resist torture.
Long-term, a situation where one side is using torture and the other isn't, or a situation where one side claims the moral high ground but is then shown to use torture as a policy is a situation where torture is a strategic disaster. The innocent lives saved by the various tactical decisions are likely to be lost - because a) the tortured and their relatives have just been turned into bitter enemies and b) the moral high ground has been lost, meaning the general population has just lost a reason to support/fight for your side.
In Safehodian terms, torturing Clyntahn might have provided a tactical advantage- the Inner Circle would've possibly discovered what the Thing Under The Basement was. But if it had ever come out that they'd tortured Clyntahn, they would've made a huge strategic loss as moderate Reformers everywhere looked at the new, Reformed Mother Church, with its new, reformed safeguards against torture and the Punishment - and compared it with the Church of Charis, now revealed to have been lying about using torture.
Remember, Nimue, Merlin and the Inner Circle have a long term goal; destroy Mother Church. There's no point finding out the identity of the Thing if they've just encouraged three- quarters of Safehold to support the Thing in its defence of Mother Church.
If Nimue and Merlin had been revealed as physically torturing Clyntahn, rather than simply convincing him that the Church and its religion was fake, the people who wondered whether the seijins are demons would've received a massive boost. Given how much the 'seijins' are used by Charis, that's a very large strategic set back. It also means that inducting more people into the Inner Circle becomes more difficult, as the evidence for the demonic nature of Merlin and Nimue is stronger - making it more likely that the truth will be seen as more machinations of Shan-Wei.
