No Country for Old Men - Just HOW Alien Is Chigurh, Really?

Okay, so I just rewatched "No Country for Old Men" and, yeah, still messed up. But I'm always thinking about sci-fi angles even when I shouldn't be, and Chigurh has always struck me as...off. Like, beyond just a psychopath. The way he moves, the way he talks, the flat affect...it's almost like he's mimicking human behavior from a textbook, not actually being human. Even the way he holds the captive bolt pistol seems... unnatural? I'm not saying he's literally an alien, ok? But the Coen brothers are masters of subtext. Do you think they intentionally built that character to feel so other-worldly, almost like an android programmed for a singular, bleak purpose? It's the lack of any real human connection or motivation beyond some twisted code that gets me. Like, Moss screws up, sure, but Chigurh feels like a force of nature, a consequence, more than a person reacting to a crime, you know? And Sheriff Bell...he's the 'old' in the title, yeah? He's the guy who can't wrap his head around Chigurh's existence. Almost like the sheriff is obsolete tech in a world rapidly becoming governed by unknown, hyper-efficient, morally bankrupt protocols, personified by Chigurh. Is that a reading anyone else gets, or am I just way too deep in my own sci-fi headcanon with this one hahaha? Curious to hear your thoughts!
