Were Dragons inherently "evil"?

Glaurung was said to be filled with Morgoth's spirit, and Morgoth was the nearest to true evil in the world.
Yet, as has been noted nothing in Arda was evil from the start. However, if by inherent you mean an evil they were from birth primed to pursue, I think the answer is yes. I do not see any other possible path for a dragon but badness. But without Morgoth, it was "evil" in lower case; not serving a prime Evil personified, but a lesser, wicked sense of personal cruelty and greed.
