Why is sincere belief a get out of jail free card? What if I sincerely believe that unless I rip the beating heart out of a living human atop a mighty pyramid every single day, Quetzlcoatl will not allow the sun to rise tomorrow, leading to 7 billion deaths? Should my sincere belief let me get away with building a giant pyramid in my backyard, despite the relevant zoning laws and without getting a permit? Oh, and should I get away with the murder thing, too?
