The ethics classes I took delved into what good and wrong are, different ways to look at things, and a whole lot of debate about the concept of ethics itself (i.e. reading old works of philosophers, including some of the weird racist ones, understanding their take on the world, and reflecting on the shifted ethical perspectives, but also lively discussions within the classroom). Everyone already knew "stealing from the elderly is bad", so things were more focused on "what are the ethical reasons to restrict free speech" and "applying different ethical points of view onto a subject".
In the end, ethics courses only teach you to be conscious about your actions and learning how to convince others that you're ethical. An ethical person can easily pass an ethics exam. All of that knowledge, and being raised by good parents, do not completely prevent someone from becoming a criminal.
If you can set up a reasonably successful scamming business on your own as a student, you can earn enough money to move to the countryside and never need to work another day in your life, as long as you can manage to hide the money from the authorities. Or you can spend it all on drugs and other short-lives pleasures, like so many criminals do.
Cybercrime targeting vulnerable people is laughably easy and extremely lucrative. Hearing about how hard some people's lives are because of their student loans, I'm a little surprised this stuff doesn't happen more, really, especially with the growing resentment the younger generations seem to feel for the bad hand they've been dealt by the older generations.
