Discussion--Dragons: Good or Evil?

[Narya]

I´ve allways imagened dragons (that are not evil) as wise and most powerful creatures, that watch the world and try to keep a balance between good and evil. Or like guardians of fate.
I like dragons very much, too. I think they are most mysterious and great fantasy- creatures.
there are bad dragons in most fantasy stories, i think this is because they are so powerful. But powerful evil creatures are not all that dragons can be. Maybe there are many dragons that use there power to protect others.
