The Morgoth-element.

[Marwhini]

I am a little confused as to how the quote of Tolkien could mean anything other than all inhabitants of Arda, other than the Ainur, as not having some component of the "Morgoth-element" given the quote I gave:

To gain dominion over Arda, Morgoth had to let most of his being pass into the physical constituents of the Earth – hence all things that were born on Earth, and lived on and by it, beasts or plants or incarnate spirits, were liable to be 'stained'.

This seems to indicate a pervasiveness of the Morgoth-element as a rule, rather than an exception.
