IGN: With Shaw killing the man who killed Root, obviously  we've seen the version of that scene where she says, "But I'm not that  person now." But I don't think it comes off as Shaw is now some psycho.  She is who she's always been. Did it just feel like, yeah, this Shaw is  not someone who would turn away in this moment? It would be a definite  vengeance all the way to the end for her? 
Plageman: I think so.
Nolan: Yeah, I mean, you don't want to be flippant  about it there, but the whole point of Shaw, as Root said to her in the  finale, she's a f**king straight line. We're not watching the redemptive  story of Shaw. We've watched the redemptive story for Root, right?  We've watched her go from being immoral to transcending, subliming  something different. With Shaw, what we love about Shaw was that she's  f**king Shaw. You could detonate a suitcase nuke on her f**king  forehead, and she'd still be Shaw, right? There's an unwavering  commitment there to her own closely guarded, tiny little moral compass,  because she sees and looks at the world differently, right? And you  didn't want to betray that. So in that last moment, for her -- and it's  terribly satisfying for us -- it isn't a redemptive, "Oh, my friend has  taught me the meaning of ..." No. Her friends were, in order of  prominence, a f**king hitwoman-turned-f**king acolyte of a transcendent  artificial intelligence, a presumed dead and missing special forces  f**king hitman, and a man who had been accused of treason. This is not a  person who learned to be nice.
