it benefits u by proving that it was a lie, or atleast proving that nat's info inst from the ability she claimed
what wud benefit town is using the kill that bypass immunity on rej/ultra/tac/cal to narrow them down. we still need multiple days to move on with the poe. why shoot someone not outed when u have couple of outed ones. if nat flipped scum, great, otherwise thats such a massive waste of resources
specially that nat is a claimed vig that can verify her role by killing someone in PoE when able
