I never use the phrase ".. ethics of a company..". Not because I listened to McNamara - what do you expect, he was the villain of our generation. No, because ethics is a part of (human) conscience, well at least in my understanding. I can imagine people extending the "concept" to other areas. Ironically Google was building an "ethical AI" and apparently failed: https://tech.slashdot.org/story/21/04/06/2154256/google-ai-research-manager-quits-after-two-ousted-from-group. Look at the timing - just days ago.Same thing with the Ferengi Rules Of Acquisition. Never heard, but seen enough. They reigned the world and filled news for four years at a stretch.
Also, similar to the conscience, ethics can not be taught. Those poor students of the law course you mentioned.
N.B. We are deep in to OT, I changed the subject line, in case the mods want to pull this discussion to the Lounge.
