How do you come to the conclusion of that being the most likely scenario? Listo's wording (while maybe unintentional) suggests more than assuming something.
Yes, but narrowing it down also runs the risk of ruling things out to soon. If you jump to the first obvious (at the time) solution then you risk not keeping an open mind about other ways the game might be set up. If it just happens to be a scum who is narrowing down everything then you might be in for an unpleasant surprise later on. Anyone may speculate, but trying to draw conclusions is pointless imo. You need to keep an open mind and be very careful of those who try to narrow down the possibilities to much.
Imo, there's a ~50 % chance Celtic's death was due to a NK. And I'd say it's max 40 % chance Decagon was killed by a Cannibal. I can see a lot of other realistic possibilities. After N2 we'll have more useful information and perhaps be able to with higher probability guess something. Until then, what does it change on this day. We could suspect from before the game started that there might be a person or a group of persons who could NK and be hostile towards the town that we'd want to vote out. That really hasn't changed a lot. Perhaps we could be slightly more certain now that there are something out there with a NK that we might want to vote out. So what we've found out is that we want to vote on someone which I don't think is that much new information.
