Do you think a potential bad actor would change their behavior if they took, say, a 12 hour course instead?

I am of course biased, but I have often been exasperated by the various "trainings", IRB processes, ethics classes, etc, that are required to run even basic psychology studies such as surveys.

Meanwhile, down the hall, the medical department is opening the skulls of mice, implanting electrodes, giving them supercancer, and then euthanizing them en masse. Often with less approval burden.

The hard truth is that it's tricky to decide what's ethical in science; we mostly allow or disallow things because they've been done that way for years, and all the added "process" is nothing but paper pushing and ass covering to quiet concerned outsiders.
