How does Kiersten White use imagery in Paranormalcy?

Imagery:

"After all, it wasn't like it was their fault they were how they were. Of course, once I thought about that, it really wasn't any of the paranormals' faults. It's not like hags woke up one morning and thought, hey, wouldn't it be fun to eat children? They were like vultures. Sure, they were disgusting and horrible, but that's just what they were."
