I'd say their personalities change as their needs change. If, as a human one would never have dreamed of attacking, let alone killing another, then in order to attack and make a kill as a vampire, one must change and become the savage creature in order to do what is required to survive. However, previous human traits must be hidden deep down somewhere, surely one can't forget that they were once a calm, rational, human being?
