Well The Dreamers are an ancient species, so they tend to have a very different outlook on things anyways. But good and evil are relevant to the acts in question. There is a Forgotten loose, Rilla has decided to craft a Forgotten character and take it in his direction. We discusses it and as long as he keeps within the general mythic frame work he can do what he wants. Which is why Skallagrim (IC) is keeping an eye on things. 

You are correct, if the Lord of Nightmares were released it would provoke another war between the Dreamers and the Forgotten/Nightmare Legions. 

The Dreamers are less good/evil as they are more observers and collectors of data. However they can and will destroy worlds or even entire stellar civilizations if they deem it necessary to further their own existence.
