Do we kill the harpy matron, or do we let her go? How do we persuade Tyrus Blackhorn to help us? Are we really so gung-ho about interrogation that we'll gleefully do so to get information out of the Scarlet Onslaught? Or if we're asked to torture someone in the name of the Kirin Tor? Do we really want to let Thalen Songweaver go ... or would we rather leave him rot in Theramore's prison?
These types of quests don't pop up terribly often, which prompts the question; just what are these moral choices for, exactly?
