Were there 7 Horcruxes -- not 6 as Dumbledore intimated to Harry ? If so , does this mean that Voldemort had an 8-part soul ?
When Harry was a baby , Voldemort tried to murder him which resulted in what would have killed him if he did n't have Horcruxes . Would n't this mean that he would have had to use one of his Horcruxes to stay alive ?
