The Fallout series has never been pacifistic, the isometric originals could allow you to become a drug addicted slave trader however they did not used to be so linear as Fallout 4 seems to be.  An inventive gamer decided to try to play the new Fallout without killing a soul and has accomplished that goal after much effort and a few bugs.  While it is certainly a blast to roam the wastelands slaughtering all those who get in your way, this article at Kotaku illustrates the problems you can face when playing a game differently than the developers expected you to.  The usual, and sadly inevitable game bugs aside, there are quite a few new ones that arise when you get creative with your playthrough.  As any DM worth their salt knows, you can never account for everything your players will do and flexibility is a must.  One hopes that devs at Bethesda read through this article and expand their creativity as a result.

"Fallout 4 expects you to commit murder. While you can occasionally avoid killing others, the wasteland is ruthless and demands violence. That’s how Bethesda intended the game to be played, anyway—but clever players are finding ways around it."
