I remember the first mission of hotline Miami. You take the phone call and learn that you are supposed to kill some people. You learn how to use your guns. You kill a bunch of baddies, quite badass. Then at the end of the mission, the screen starts swaying more than usually, and the protagonist vomits in an alley. Of course, he just killed for the first time, overwhelming. Makes him quite human, more than many other protagonists, despite the pixel art style.
I have very vague recollection of it being relevant…
