Moral education

Recently, I read the local news that two young person [ a lady-scholarship holder and a man ] were charged for walking nude in the district called Holland village. Both were fined for improper behaviour.
Luckily, this was the rare case here. I am wondering what are their motive? They said that they wanted to feel the thrill.
Both of them are highly educated but they have zero moral concept.
Proper moral education should be emphasized especially in this century.
What do you think?
