[Lord of the Rings] Are all Dragons evil? Could a Good Dragon exist?

I'm sure this has been covered, so far as I recall the first Dragons were malevolent creatures. That being said, was there/could there (hypothetically) have been a "Good" Dragon, one aligned with Middle Earth against Morgoth and Sauron etc? Was Evil an intrinsic part of them?

Are they Evil in the same way the Orcs are, just totally twisted with sadism and cruelty worked into the very fiber of their beings? Explanations appreciated.

During the First Age, Morgoth knew that his orcs weren't sufficient against the host of the Noldor. Hence, using fire and sorcery, he created wyrms of great power. The first of dragons, Glaurung the Great Worm of Angband, the Golden, the Deceiver. It was Glaurung who orchestrated for the children of Huron to unknowingly marry one another. It was during the War of Wrath, that Morgoth revealed one of his greatest creations, the great winged wyrms, chief among which was Ancalagon the Black who broke the assault of the Hosts of Valinor until Earendil and the Eagles slew him on the slopes of Thangorodrim.
