What songs are there where a moral is given right at the end? For example, in The Ballad of Frankie Lee and Judas Priest by Bob Dylan the last verse goes:

The moral of this story,
The moral of this song
Is one should never be
Where one does not belong.
So when you see your neighbor carryin' somethin'
Help him with his load
And don't go mistaking Paradise
For that home across the road

There's also "Cedars of Lebanon" by U2 which ends with "Choose your enemies carefully 'cause they will define you/ Make them interesting 'cause in some ways they will mind you/ They're not there in the beginning but when your story ends/ Gonna last with you longer than your friends"

I can't say it's something I've heard in many other songs.
