It might occur to you that the power of Durable Evil is a banal thing for a vampire to set his fangs on.
Evil is rather common, after all.
It's been done. It might cross your mind that the people who think Vlod isn't focused entirely on Lenore, the rare and radiant maiden with the big webs, are the sort of people who would buy a bridge on the internet. You might be right. Why would a vampire risk his corpse for the power of Durable Evil, which has been freely available to all comers for many years now, ever since the Yankees lost the pennant. Everybody uses it.
