All this debate about vampries having souls. Are we going to ignore the original saga? Bodhi? Her and Irenicus were stripped of their elven spirits, and in her case, she turned to vampirism to compensate for its loss. Since vampires don't have souls, she had the option of being an incomplete elf or a complete vampire.
Yes, vampires don't have souls in D&D. It's part of the plot of Baldur's Gate II.
Larian is just playing fast and loose with the lore of the setting in a number of places. They changed vampires to have souls because it was convenient, just like they made mindflayers *not* have souls because it was convenient. Both contradict prior lore, and it's far from the only instances.
