There's actually a very good scifi story idea here

I doubt it. Our own sense of disgust is protective, to keep us from getting poisoned or infected with a contagious pathogen, or in the case of seeing violence, to keep us safe from that very same threat.

Even if we instil AI with survival objectives it'll learn to avoid things that are dangerous to it, while still being able to operate, say, our sewage and waste disposal systems without having a visceral response to the material being processed.

That doesn't fully make us safe from AI deciding we're too degenerate to live. An interesting notion comes up by recent news of an Air Force general saying USAF AI is trained on Judeo Christian values. And while that doesn't mean anything, I could see an AI-driven autonomous weapon (or a commander-AI that controlled and organized an immense army of murder-drones) being trained to assess humans based on their history of behaviors, destroying sinners or degerates or perverts or whatever.

Given we humans are a vengeful lot (Hammurabi's code an eye for an eye was to set an upper limit on retribution, claiming an eye rather than killing their family over the incident) it would be very easy to set judge bots to err on the side of assuming guilt, necessating punitive action.

AIs going renegade can always be attributed to poor programming.
