> This would make cartel execution videos more abhorrent?

I don't really wanna get into a hierarchy of abuse/violence; let's just say they're both bad. But watching a video of a beheading isn't beheading someone. We may have a moral objection to someone deriving pleasure from the watching of it, and we may even worry that without regulation we'd create a market for this abhorrent act, but it's still not the same thing.

> Why would watching or possession of evidence of abuse against a person be an offense against a person?

I didn't say this. I said CSAM is evidence of abuse against a person in a way anime can't be.

> I think it's perceived as abhorrent mostly because it's an evidence of the person watching being sexually interested in kids.

Yup, it's moral outrage. I'm not saying that's good or bad--personally I think there isn't enough moral outrage these day. All I'm arguing is the way we treat people who have CSAM is pretty unhinged, and it's even more absurd when we talk about AI-generated CSAM and like, loli hentai or whatever.
