No. People definitely do immoral things knowing they are immoral.
But if you are incapable of understanding anything, as I believe LLMs are, then you are incapable of understanding what is moral and what is immoral. This is why we have carve-outs in the law for insanity or cognitive impairment.
> In this case, many, maybe most humans are "not intelligent". Human can admit it when what they did wasn't moral and so can LLMs.
You can teach a parrot to curse, but that doesn't mean it's angry.
Of course they can classify certain actions, including their own, as moral and immoral if you give them a reference point. They probably do it better then some people. The question is how do you prompt this behavior, but that's a technicality in the harness design more than it is a fundamental problem of the LLM as a thing.
