It seems there are quests that force you to murder innocent people (Daedra quests) without an alternative.
I wish these types of quests would have been written to give you a choice, for example defying the Daedra lord and letting the prisoner escape.
You would suffer in the Witcher games!
Yeah.. but it would be nice, just like back in good ol'Morrowind times. But that's life even in Tamriel. According to the Lore, Daedra's are mostly evil so we can't expect them to be merciful, etc..
I defy Boethiah by hunting down her followers

and by not completing her quest.
