Haha, it's not final, the idea is still very sketchy. Basically, since the New Dawnguard killed many undead before they were turned, kinda as a compensation for their turning (which was done by vampires on accident when they left the members for dead), Meridia changed their vampirism. It isn't so much they get the vamprism to kill vampires, but rather they got the vampirism while killing vampires and prayed to Meridia to clear it.

In fact, this is also a source of the ideology split. The Old Dawnguard is godless, the New Dawnguard worships Meridia
