Something I'm wondering about how to canonize my character. One of my save files with her had her joining Clan Volkihar in the hopes of somehow being able to influence them to aid her in other areas, and also living forever. After the inevitable disappointment on the first front, as I can't even count the castle as a residence (also beating Dawnguard way too early, at level 20, thus making Vyrthur and Harkon into low-powered paper tigers), I started wondering about the morality of this.
I don't believe that becoming a vampire is inherently immoral... my only motivation for it was immortality, not the allure of preying on people. However, the Volkihar are clearly up to some rather immoral things themselves, if the human cattle are any indication. If I control the clan after dealing with Harkon, I'd love to be able to reform it, but I'm not sure how I'd go about rationalizing this. The quests themselves aren't necessarily as bad; even the radiant one involving framing the Dawnguard is all right if you get the Markarth quest, as one of the prominent citizens you can murder is a member of Namira's cannibal cult (something that seems downright quaint to a vampire lord). However, after playing with the Dawnguard in another file, I grew to dislike ruining them, as they seem like decent people overall... I also wasn't fond of enthralling that Moth Priest.
