First of all, please don't spoil the quest for me or people involved with it. I want to do this the right way.
Situation is this: I know that there is a quest involving cannibals in Markarth, and it starts by getting along with Eola. Until now I have always just cut her in half every time I meet her but now I want things different because I hear there are a lot of other cannibals as well in Markarth.
What I want is to find a way to proceed the quest until I would expose all the cannibals in Markarth, and then butcher them all. Is it possible? Or is this one another quest that I can't fail no matter how hard I try.
I know the quest involves hunting down some dude and then eating him with Markarth's cannibal population. That's when I would intend to put them all to sword and ditch the quest there.
Just tell me if it's possible or not.
