all-might could self-hammer if he thinks it might avoid killing an extra player
at this point though we might want an extra player killed
although i guess the probability of vengeful hitting scum is low if scum knows all might is town, since they can avoid hammering and even avoid being on his wagon, and it being telling tomorrow won't matter if the game is over
idk if self-hammer is a good play or not, even if it would work
if all-might is scum vengeful he'll just refuse to hammer himself and it'll go to a no-lynch before it'll result in a dead all-might sans vengeful
