This question is prompted by the movie Operation Finale, about the capture of Adolph Eichmann by Israeli agents in Argentina.
Important scenes in the movie show Eichmann arguing that his acts in WWII were those of someone defending his country against its enemies, and were no different than those of the Israeli operatives who captured him. They, too, were defending their country (Israel) against its enemies. Eichmann was clearly equating his role in the Holocaust (a word I don't think he used in the movie) with the Israelis capturing him in Argentina and extracting him to stand trial in Israel. At a minimum, and ignoring torture and starvation, Eichmann was off by a factor of 6 million.
As I listened to this, I thought what sophistry! But sophistry isn't strong enough for the moral tone-deafness of that argument. Just going from the portrayal in the movie, I would say he is actually insensible of the difference.
Sophistry, from Oxford Dictionaries:
The use of clever but false arguments, especially with the intention of deceiving.
‘trying to argue that I had benefited in any way from the disaster was pure sophistry’
The synonyms for sophistry from Dictionary.com are even more wishy-washy:
deception, fallacy, misconception, subtle argument
Further synonyms from the same link, also wishy-washy:
casuistry: overgeneral reasoning///chicanery///deception///deceptiveness/// delusion///equivocation///evasion///fallacy///lie///oversubtleness///sophism/// sophistry///speciousness///spuriousness///trick.
Is there a word, phrase or expression which expresses the moral repugnance of this argument and the monstrous moral cognitive blindness (in the phrase of @MetaEd?
Obligatory sentence: Eichmann's arguments were the absolute nadir of _________.
If there are uses of sophistry in a commensurate context, that would be a useful answer.
