Over the weekend, I decided to take on a few of the daedric quests. Specifically, I completed Azura's, Boethia's, Namira's, and Clavicus Vile's quests. The lore of TES states hat the daedra are the evil counterparts to the Nine. While some of Morrowind and Oblivion's quests showed this side of the demon princes, I think that Bethesda's stepped it up in Skyrim.
I didn't kill the dog Barbas to keep the Rueful Axe, figuring that not killing him would get me the Masque of Clavicus Vile. I don't use axes anyway, so that was an easy choice. Still, that was one nasty choice.
I didn't have any issue killing Boethia's followers, or her former champion. However, I do feel really bad that I paid a mercenary to follow me, just so I could stab him in the face. The animation of him becoming bound to the stone was pretty disturbing, and that Boethia uses the dead body right away was pretty eerie. All in all I really liked that quest, but it was still uncomfortable.
The quest that I really had to sit and think about was Namira's quest to kill and eat a priest. I led the priest to the feast, and stood above him, deciding whether to eat him or kill everyone else in the room. I have a no-reload policy for these types of decisions, so I assumed that I would fail the quest if I did not eat him. Ultimately, I want to S-Rank this game, so I decided to go ahead and eat him so I'd get Namira's boon. I ate a dude to get achievement points. That's messed up.
