Fan Casting Halle Rivers in Ill Omens

Halle Rivers A.K.A Demon, is a mercenary, vigilante and occasional thief. She is funny, and charming, but a confirmed sociopath, though it goes unnoticed since she doesn't exhibit a lot of sociopathic behaviors. Many of her friends wonder if she's also a psychopathic due to the fact that she exhibits psychopathic traits, but it was never confirmed. She was raised by her mother, also a mercenary. Her mother planned on killing her father, and when she carried it out, both her and her big sister were forced to help kill him; this is likely what caused her sociopathy, though her sister doesn't seem to be burdened with sociopathy or psychopathy.
