While children as young as seven have an innate belief that copying someone else’s work is wrong , students may have trouble seeing plagiarism the same way because it feels like a victimless act. If nobody is hurt then we are unlikely to feel empathy, and without that it’s hard to see something as being morally wrong.

Cyberbullying may be the area where parents and teachers are most concerned about kids behaving ethically. Though it’s not yet clear if digital media have actually increased how much bullying is going on, there’s no doubt that online bullying can have a much longer lifespan and reach a much larger audience than traditional bullying.
