Sauron was not some romantic idealist and he did not harbor any remaining feelings of loyalty or affection towards his former master.

The thought occurs that for Sauron "bringing back" Melkor would have had just as little appeal as Ëonwë's instruction to go before Manwë for judgement: he would go back to being a slave.
