Bringing back teaching on moral lessons is a dangerous thing to do. There are many reasons why teaching morals through coursework could be problematic. First, morality is all relative, meaning that anyone can create their own sense of morals. Therefore, if two teachers disagreed on what "true morality" was, then there would be a dispute and students could be confused. Furthermore, if someone in power wanted to create morals that only benefited themselves, they could require teachers to teach a biased "true morality." All in all, there is not enough concrete data for schools to teach students what "true morality" is because few people can agree on what "true morality" is.
