.Hermione_Granger. Why didn't Voldemort come back as a ghost? A ghost means a ghost is the soul or spirit of a dead person or animal that can appear to the living. Voldemort, could not come back as He was soulless, He split his soul into, 8 parts (he made 7 Horcruxes, but the 8th part was in his body) All his Horcruxes were destroyed. A ghost is basically the soul of a person and making Horcruxes. As Hermione said, "A Horcrux is the opposite of a complete soul" Voldemort made Horcruxes, by making Horcruxes, he ensured that he could not come back as a ghost, as a Horcrux is a complete opposite of a soul, and a ghost is basically, the soul of a dead person.
