I'm having a tough time figuring out how I should handle this. I'm in Uttering Hills Cave, and I'm ready to go in. I'm just wondering whether or not I should kill the Shadows. Here are some details, and tell me what you think I should do.

The Thieves Guild has a code of no killing, and staying true to it could be good RP for my character. Your character will also explicitly mention it during this special mission.

My thief is a former Summerset Shadow, and while she is not vengeful, she has had a rough past with former "friends" who turn traitor (Mercer Frey, Jaree-Ra, and now Linwe)

She left the Shadows after Linwe threatened her life after botching a job, and losing the spoils. (Backstory is still a WIP )

You do not have to kill anyone during this quest.

Linwe would kill her on sight, if ever given the chance.

I'm using this build, which is rather pacifistic: http://theskyrimblog.ning.com/group/character-building/forum/topics/character-build-the-summerset-shadowhttp://theskyrimblog.ning.com/group/character-building/forum/topics/character-build-the-summerset-shadow

I also would love to have Linwe's armor. It looks awesome and has viable enchants. (I only break the no-looting-dead-bodies rule in the build for unique or required items)

So what do you think I should do? Sneak all the way through, snag the locket, and get out, should I kill everyone, or should i find another way?
