We could abstain for 3 rounds. 6 innocents would die.

We could vote for 2 rounds. 4 innocents would die, + 2 more would probably die, but we have the chance at hitting a mafioso.

Therefore it is to our advantage to lynch, even without taking into consideration that rounds without discussion are useless. Also, in Mafia IV we lynched a mafioso round two on the same kind of weak evidence we lynched Drisos with this game.
