There's a picture of him helping her decorate the Christmas tree when she was a little girl, and god it's chilling how ordinary, harmless and trustworthy he looks. If a guy who looked like that knocked on your door with a big friendly smile and pretended to be the plumbing inspector, you wouldn't suspect anything at all. Paolini and his like do us a disservice by childishly pretending that an evil person always looks ugly and crazy and goes around cackling and kicking puppies all day.

True evil can look like anyone. Including your dead old dad with his dorky glasses and Ned Flanders moustache who helped you decorate the Christmas tree.
