So, I assume you call a good example a "role model." Then, what do you call bad examples?

You would call them exactly that, "bad examples!" When talking about someone who isn't a good influence, it's common to call them a bad example or even a "bad role model." It sounds quite natural in conversation! Ex: You shouldn't do everything Jerry does. He's a bad example. Ex: You've never been a good role model to your siblings.
