It is a false myth that Vampires don’t have souls or lose their human souls once they are transformed into a dark bloody immortal. It’s only technically true for First-Generation Vampires, and their pure bred offspring, who have demonic souls that reside in Hell. Otherwise, a vampire that was once human has a soul. Certainly, they are human in the majority of Parallel Universes within this Multiverse since being a vampire is quite rare. Even rarer than becoming a celebrity. Human souls are unified spirits comprised of their near-infinite lives lived out in all the various parallel realities, and dimensions. All mathematical probabilities are played out within a certain parameter determined by various higher dimensional Gods, and even ourselves. Therefore we’ve all been vampires in some other Universe yet we clearly still have our souls in the afterlife.
The Soul Technicality
Despite vampires not losing their human soul they are in essence cut off from it. Their human DNA becomes demonic based, and their normal Astral Energy body is replaced with a dark demonic body of metaphysical energy. Evil energy linking them to the patron Demon who originated their particular line of vampires. This dark energy, or vampire spirit, more or less hijacks the connection to their higher dimensional Heavenly soul. It instead creates a new connection to Hell that is more direct than the connection to their human soul. This along with the inbred urges within their demonic DNA results in many vampires living their immortal lives on the dark side. Thankfully there are some vampires who reject this demonic connection. Those who are subconsciously in tune with their human soul because free will is still a factor. These good vampires often fight against the forces of evil turning the tables on the continued effort to recruit new demonic minions.
