[LOTR] Why did Sauron have his minions worship Morgoth instead of himself?

Morgoth is out of the picture so Sauron doesn't need to worry about being put in his place by Morgoth.

From Letter 183:

> When [Sauron] found how greatly his knowledge was admired by all other rational creatures and how easy it was to influence them, his pride became boundless. By the end of the Second Age he assumed the position of Morgoth's representative. By the end of the Third Age (though actually much weaker than before) he claimed to be Morgoth returned.
