...We hung others for it actually, but it's okay now it seems, for them and for us. Happy days.
I'm pretty sure that 'torture' was not the cause of those death-sentences in the 1940s.
Rather, it probably had something to do with genocide -caliber mass-murder.
Torture was certainly on the menu of charges but I don't remember anybody being hung simply because of it, stand-alone, without murder being involved.
Torture was more like the condiments on a hot-dog rather than Main Course.
No, torture, which is a war-crime, is what they were charged with, and waterboarding was on the list. Look it up.
Nolo contendere.
No contest.
I merely say that nobody (within the context of Nazi war criminal trials) was hung
ONLY because they engaged in torture.
In refutation of your earlier observation.
Unless you can drum-up somebody who was charged
only with torture - or acquitted of everything
but torture - and still hung.
I recall no such person, and my first guess is that you will not be able to come up with one, either.
