Do you generally avoiding initiating violence and gore, unless it is to kill for items?
Do you completely avoid bloodshed by sneaking past any foe?
Do you only kill if attacked first?
Me, I usually fall into the last category. Not that I walk the straight and narrow all the time; my character is a highly accomplished thief, she simply does not get caught and always maintains a 0 bounty (without having to resort to having the guild remove it for her).
