# Are engineering ethics objective or subjective?

I recently asked a question about the ethics of a situation. Some of the answers surprised me by suggesting that if I could sleep at night what I do must be ethical. This is not consistent with my understanding of ethics. I understand ethics to be an objective set of rules describing expected behavior for a given profession. Which of these is correct?

The community needs a clear answer to this question, even if not in my question particularly. If ethics are subjective, they are not properly in scope for a site based around objectively answering questions.

I believe you are referencing this answer

The question you have to answer for YOURSELF (not your company) is will you be able to sleep well if one of these guys gets fried? Since the customer has disclosed his unsafe intention, I think that you should not feel obligated to provide the part. Yes, he may just go elsewhere to get the part, but that is on him.

And to be honest, that's not the greatest answer I've ever seen for a situation like this. It is a lot bigger of a question than being able to sleep at night, because Professional Engineers are held to a higher standard than the "Can you sleep at night?" test.

If we look at the National Society of Professional Engineers Code of Ethics, specifically Section II, Rules of Practice, we see:

1. Engineers shall hold paramount the safety, health, and welfare of the public.
• If engineers' judgment is overruled under circumstances that endanger life or property, they shall notify their employer or client and such other authority as may be appropriate.

And it's very clear that there is a stated obligation upon the part of the PE to contact the client in cases where life or property is endangered.
