Aw, come on, don't sound like a troll. Don't argue for the sake of arguing. THere is a big overlap between ethics and laws. Just because some items don't overlap doesn't warrant such a statement.

Seriously? Theft, Assault, Civil Liability etc.. I think there's a significant overlap between Ethics and Law. Our systems of laws are based on the work of philosophers studying ethics, of course there's a huge overlap

There's also offshore tax havens, political action committees, and patent trolls. Some unethical things are legal.

There's also underage sexting, media piracy, cryptocurrencies, and marijuana. Some things aren't globally agreed upon as ethical or unethical, but the law still attempts to address them.

Identifying the overlap is difficult.

people create laws to enforce ethics, but ethics and laws and law often don't overlap because law gets tinkered with less than ethical people and one man's justice is another man's horror.

I agree with you, they definitely don't match exactly. But I was arguing that they overlap: Some parts match, or at leats cover the same ground.
