Loreheim
As far as I'm concerned his "sister" is worse than his father, she knowingly and deliberately manipulated and used someone who loved her dearly and tried his best to give her a happy life in order to strike at a man that they both despised. She is so much lower than Crowley that it isn't even funny, as much as a monster as he is he still feels a deep attachment to his his children, even a child he never raised and was crushed when he realized what he had done the second it happened as he had thought the one who found him was his enemy. I also think that Aiwass knew exactly what was going to happen the second it started helping Roy transcribe the Book of Law. Laura on the other hand spend at least a decade with Roy and acted as family, she literally raised him as a lamb for slaughter and only felt a bit sad a few hours after he had gotten killed while trying to save her from a demon possession. It makes no sense that Aleister should get his due worse than her, Aleister may have pulled the trigger while metaphorically blindfolded but Laura was the one who's manipulation intentionally put Roy in front of the muzzle and loaded the gun. Worst of all it wasn't even to kill Aleister, she acknowledged that it was all done just to cause him despair. She tricked an innocent to commit metaphysical suicide just to make someone else suffer, that's just vile.
