Today a friend referred me to an essay by Isaac Asimov entitled "The Relativity of Wrong" with which I was not previously familiar. It contains of Socrates which seems right in line with the Epicurean perspective. Even more than that, it contains an analysis of what it means to be "right" or "wrong" that I think is probably also very consistent with Epicurus' perspective. Here's a good summary of the point from Wikipedia ("In the title essay, Asimov argues that there exist degrees of wrongness, and being wrong in one way is not necessarily as bad as being wrong in another way")
I don't know anything about this website that has a copy other than that it comes up first when one searches for the author and title) but here it is in easy to read form. (Let me expand my caveat - I haven't vetted any of these websites I am linking to - I just see on their face that they address this topic.)

Looks like it can also be read here: https://skepticalinquirer.org/1989/10/the-relativity-of-wrong/
There's also a copy on Archive.org
Some criticism of the article here.
Seems to me to be an enjoyable article and well worth reading.
