I think you’re taking the professional responsibility that engineers are given too far. They are not given that responsibility to make political decisions, as you seem to be implying. Engineers are professionals in the hard sciences, not in social sciences. They only have power over ethical and safety issues directly pertaining to technical matters. I think ethics in this sense includes only very widely accepted ethical opinions, not anything that people from different political parties would disagree on. Engineering, in other words, is not political. Making the world better, as you put it, is something that requires political decisions. I hope people don’t make this confusion because the last thing most of us would like to see is Engineering becoming a political endeavor, including software engineering.
You're the one that brought up politics. You're right that they're hard to decouple from ethics as that's essentially how the parties form.
But where I disagree with you, and extremely, is that we should not have our own personal ethics and adopt that of what we believe is society's. You're asking the impossible. Such a thing doesn't exist. Whichever country you're in you'll find a diverse set of opinions. The most universal ethics are only the most basic. But if it did exist I'd still disagree as you're asking engineers to not be human. You'd be discriminating people based on religion. You'd be discriminating people based on culture. You'd be discriminating people based on their humanity. I'm extremely opposed to turning humans into mindless automata. Everyone has the right to their own beliefs and this is our advantage as our species.
Well interesting... I absolutely expect engineers to make the "right" decisions no matter their religion, race or culture. It's not about being mindless automata, it's about using scientific rigour to guide your decisions. Engineering is the application of science to real problems. I don't really get how you can disagree with that, but that's fine, we're humans and we will never be able to all agree with everything others say, even when we're only talking to other engineers :). So I'll give you that.
