I don't consider sacrificing a humanoid who trusts me to be not evil. 

So, take somebody you don't trust. A drunk you brawl with or a sellsword. Marry Camilla? Take Sven/Faendal. Besides, death is an eventuality.





I have less of an issue killing them face-to-face, but I'd feel a little weird 'tricking' someone into following me up there...even for money. 


...I don't have that perk. 



...or maybe I'll just Smith a bada$$ Daedric Great Axe and trade him if I can get his quest.
