ArenaNet:Guild Wars 2 suggestions/Dragons Not Truly "Evil"

(Discussion)
In the Movement of the World article, the Dragons are evil creatures who want to destroy the world. If the Dragons were always like this, then why hasn't Tyria been destroyed. Maybe the Dragons at one point were good but during the events of Nightfall they got corrupted and became evil. Since during a cut scene it says that "Torment washed over Tyria" maybe that meant ALL of Tyria and that the Dragons were corrupted during their slumber and were woken up but instead of wanting to fight against the Torment want to fight with it. So instead of Primordus fighting The Great Destroyer, he makes him one of his Generals. Since the Dragons existed since the beginning, why haven't they already destroyed the world? Are they fearful of the gods? Are they biding their time? Or were they just misunderstood? Just a suggestion, since it isn't explicitly said whether or not the Dragons were always bad.

I think this also should be a good idea.
 * Why this is a good idea
 * Would expand Dragons role in Tyria
 * Would explain backstory tointerlude between GW 1 and 2 (Gathering their forces etc.)


 * Why it may not work out
 * Dragons were always evil, just never had time to wake up and blow everything up
 * Dragons were sleeping because they didn't want to have gods destroy them
