There is a subtext of Christian allegory in "Blade Runner", particularly in regard to the Roy Batty character. Given the replicants' superhuman abilities, their identity as created beings (by Tyrell) and "fall from the heavens" (off-world) makes them analogous to fallen angels. In this context, Roy Batty shares similarities with Lucifer as he prefers to "reign in hell" (Earth) rather than "serve in heaven". This connection is also apparent when Roy deliberately misquotes William Blake, "Fiery the angels fell..." (Blake wrote "Fiery the angels rose..." in "America a Prophecy"). Nearing the end of his life, Roy creates a stigmata by driving a nail into his hand, and becomes a Christ-like figure by sacrificing himself for Deckard. Upon his death a dove appears to symbolise Roy's soul ascending into the heavens.
