Do you mean in all areas of life or specifically companies / shareholders?

A person cheating on their spouse would pretty commonly be considered to be doing something "immoral"

Yet it would be ridiculous to make something like that illegal

I think the attempt to make moral and legal always align creates plenty of hazards itself

Especially if the moral code the law is based on something external and nowhere near universal (like religious sources, which disagree with each other, etc)
