I was watching Thor again and noticed something odd. Midway through he movie. I noticed after Thor trying to retrieve his hammer. That they were looking through a children's book with stories about Thor and such. One page caught my eye and it had Loki on it with I think it was a snake behind him. Meaning he is a Evil character. Now see in the movie to this point Loki's character is still being built and he is not yet totally evil. But the book already says he is evil yet the book was written way before all this has happened.
