I don't think the dragons are being portrayed as evil at all.
Alduin is both the creator and destroyer of the world. Shor and Dagon(/Magnus?) messed up the natural cycle with the forming of Mundus and now he's just going to try to finish what he started ages ago.
Also, I get a creeping feeling the dragons are the Jills; Didn't they say there was some sort of time-slowing effect from killing one?
EDIT: One more thing, from a Merish perspective, Alduin and the dragons are the good guys.
