Dishonoured 1 had a few like that.Gameflyed it over the long weekend and finished up a no kill no detection play through on normal with Emily in about ~12 hours. Did a murder run through not caring who saw me after and it took like an hour or so since I knew all the routes at that point and exploited the hell out of the domino and ash powers. The non lethal take downs on a couple of the named targets seemed crueler then killing them which was unexpected. Probably sometime after the holidays will give a no powers no kill run a try with Corvo as the replayability and speed running categories seems high with so many different ways to approach things and lots of odd little interactions between NPCs depending on what you have done in previous levels. If they iron out the PC version I'd pick it up in an instant, it really feels like what that Thief reboot should of been and makes me wonder how I missed out on the first one.
edit: The one thing I really wish this game had was a new game plus as I don't think it is possible to unlock everything in one play through and it is always fun running through these type of games like a God after the first clear.
The non-lethal means to take her out, is to render her unconscious, then deliver her to a stalker, that kidnaps her, and takes her back to his estate never to be seen again...
so yeah, you give her over to a stalker/rapist.
