Um, er,.... [looks shamefaced]....
I fleeced everybody with exception of two: the people wandering the streets looking for food and scraps - who wore purses. I DID feel utterly horrible one time when I tried to talk to the woman on the waterfront but forgot I was crouched - and instead of speaking to her the action swiped her purse. Oh EVIL!!! It's a game - yes, only a game, but I think that was the biggest moment I wished for an "Undo that horrible thing you just did" button.
Now there's an idea for a new Dishonored game: the objective to snatch all that gold from the likes of Boyle's place and give to the needy as they rebuild Dunwall.
