You can break the law and not do anything wrong.

In fact, there are laws which most people would agree are wrong not to break. Legality and morality/ethics are not the same, not defined by the same peoples and if anything are growing more and more separate. You and I don’t play any real part in designing the laws, they are not some liberal-democratic ‘will of the people’ as I’ve seen lots of people elsewhere saying. They are the dictatorship of the politicians, and more so, of the mega-wealthy class that own them.

This is what happens when universities stop offering ethics in their courses

If you want professionals to not give a shit about ethics, call one of the courses “Ethics in [career]”. It has to be ingrained throughout education (let alone society). Universities are not the cause.
