Cain in the modern world

I'm still reading Ari Barak and the Free-Will Paradox by Shaul Behr. One of the major plotlines is that the protagonists time-travel back to biblical times, meet Cain, and inadvertently bring him back with them to the 21st century, where he causes chaos -- "raises himself," so to speak.

Early this morning, I received an email from WordPress notifying me of a new "like" on one of my old blogs. Clicking through to the blog of the person who "liked" my post on Dante, I found an October 14, 2025, post titled "A Short Story: I watched Cain kill Abel." This is not a time-travel story but seems to place the events of Genesis in the 21st century. The narrator (who we are to gather is delusional) mentions living in Brooklyn, being interviewed by The New Yorker, etc., but also speaks of Adam and Eve, Cain and Abel, as contemporaries and, as the title indicates, recounts personally witnessing the murder of Abel. This paragraph will give you a feel for the way biblical events are discussed in the story:

Adam and Eve’s banishment, when it happened, needless to say, attracted many international headlines, and the capacity in which I visited the land east of Eden was that of an “activist”, as I sought to convince the local governance (with my fellow “activists”) of Adam and Eve’s innocence. It was, at that point, still a political issue; and one that had spread globally. Little did it help, however. After weeks of ineffectual campaigning, it seemed Adam and Eve’s banishment was as decided as the sun was to rise in east, so, the activists simply, realising the fight was lost, went home.

Stories that place Cain in the 21st century -- whether via time travel or only in the disturbed mind of an unreliable narrator -- are surely few and far between.
