OK, ethics and morality are part of nature because humans are a part of nature. I don’t see how that changes anything else about this discussion. Humans still have a sense of right and wrong that does not (as far as we know) exist elsewhere in nature.

In any case you are now getting into semantics. What does “right” even mean if not morally and/or ethically acceptable? If it simply means “what is” then it has no meaning, since nothing that exists can be wrong.
