Read an archive of the article since I was wary of Kotaku, but for those interested, the guy set out specifically to not kill anyone, and achieved this by avoiding "objectives" of the game that weren't technically necessary. The game might giv eyou the objective to kill some raiders before it tells you to go to a spot, whereas he knows where the spot is beforehand and skips the kill areas.

In other situation, he would deliberately engineer situations to have other people kill the "need to die for plot" characters so that he could maintain his clean-slate (nulls it in my eyes, but whatever).

The guy is quoted calling out Todd for not understanding how his own game works because it was easy to circumvent mandates from the game that "need" to happen in order to continue.

The rest of the article is Patricia Hernandez, Journalist Extraordinaire talking about how Fallout mysteriously had glitches while the guy was doing this, and for some reason that's important and implies something despite weird glitches and bugs being a staple of any Bethesda game released in the last decade.
