Oh trust me, once you get into the Dark Brotherhood quests, you either have to stomach the murders of innocent people or get out!!

Oh, I did all of those and am done with it. I just thought I had a choice in being good or bad. Didn't realize it would cost me the platty though!!
I'm still trying to be the good guy.
So far I've accidentally stolen a bucket (the owner promptly took it back from me, lulz) and shot a Whiterun guard in the head because at a distance I thought he was a bandit. In my defense, I had just fought two bandits and knew there were two more in the area, so when I saw him moving it was the most natural assumption.
Basically I'm bad at being good. :(
Lol. I steal stuff all the time. However, I have so many "friends" in this game that most stuff is given to me for free at this points. Seriously, I am swimming in resources. Once you complete the stone quest you find gems everywhere and figuratively have mulah coming out of your ears!
