As no Ainur, but of Maian stock, his understanding of creation as an offspring of Eru's thought, was limited, I imagine. I recall reading that Sauron was a Maia of Aule's lineage, originally, which was all about craftsmanship more than living (though look at the Dwarves--Aule's creation--pretty awesome really). By the time Sauron had corrupted and ruined long enough, he also lost the ability to assume fair form. Another theme Tolkien seems to replay over is about devolution of power, or about a kind of 'one way' path a Maia can take (e.g. Melian, when she assumed Elvish form, kinda got caught at that evolutionary point). Melkor lost the power of shape changing at some point I seem to remember....
