Tolkien's original sin comes from creation, when Morgoth was trying to usurp the song and introduce his own creative elements. Judo-like, Eä accepts and incorporates those themes to produce something yet grander.

So there are threads of corruption running through potentially everything in Middle-Earth: Men, Elves, Dwarves, whatever. And what you do in the face of it counts for more than its mere existence.
