Mmh. Yeah, Molag Bal is, more than most, viscerally E-ville. His quest in "Oblivion" involved corrupting a retired paladin. His quest in Skyrim involves beating a defenseless, trapped (if irascible) old man to death with a rusted mace. He's got an impressive record of leaving me feeling dirty on the basis of wholly fictional acts.
I don't think I'll be taking part in TES Online, though; for me, much of the fun of the series is the permanent impact you can leave on your surroundings.
Actually assassinating, for instance, named, unique NPCs who have an existence outside of the quest line is sort of anathema to an MMO, which must necessarily have either a persistent or persistent-ish world (lest some merry psychopath depopulate all the NPCs).
Also, TES has always treated death as permanent, the only exception being ... um, dealings with Molag Bal.
Oh, dear. Well, that's one way to explain a respawn mechanic.
Ah-- there are also acts of the gods, ala Knights of the Nine, but that's ... less ... common? I think?
