You don’t need people to give reads to udnerstand theirs aligment.
And not everyone is good in making reads to begin with.
You can just as well be there to help people create ideas, and the way you influence the process is enough of a hint for aligment of that person.
If you reinforce someone in idea of scum being scum, or you save a townie from badly constructed lynch, it’s just as good proof of being town as lynching scum by yourself.
Even better tbh, since you are not directly and visibly doing it (possibly for town cred), but you help others.
This is how mafia was supposed to be orginally plaied.
By cooperation, not by duel of charisma to see who pushes own PoV through.
