I chose to do a violent playthrough. I regretted it later on when I saw Emily's drawing and saw the ending. Turns out it wasn't dark, it was pitch black [censored] it.

I've never planned on doing a high chaos run because I don't enjoy playing that way but if I was ever curious about the ending for it, I'm not now, thank you. I did a low chaos game and had no kills until I goofed and rewired a security station incorrectly. No one ever died by Corvo's hand though. I was very happy with that game and would do it the same way only better next time. I could tell I missed a lot by the end-of-mission screens so next time, it'll be about being more thorough. It was a great story and I really enjoyed being in it....the end scenes were good.

I prefer the True High Chaos ending. But I like playing non-lethal more than lethal.
