Depends on how the classes are offered.
I think it would be nice to have a class on "World Religions". Teaching an overview of each religion and ways to respect each other.
As far as "Morals" go, it would be more effective as a class in "Objective Ethics". Where Morals tend to be "What we do" . . Ethics might be more informative in "What should we do". "Objective" weighs in with what might be socially acceptable behavior for all.
Usually, morals is something one learns in social interactions and from your parents.
