That's imposing fear. How is that, in and of itself, moral? If someone can't tell the difference between right and wrong, they lack empathy. Not fear of something. If they are acting out of fear of personal punishment, that's a pretty selfish reason to do the right thing. Do the right thing because it's considerate(empathy). Not because you're worried about punishment. If that's the main thing keeping someone from doing what's wrong, I seriously question how good of s person they are to begin with.
