I had an idea, we could replace the regular citizens (I don't really want them to be in my game without a special ability – they're not very interesting).
Here:

Homeless person – an elderly man nicknamed *Stinky*, who constantly attracts attention.
Special Ability: Checks for special abilities; if he sees one, he kills, dies himself, and kills the killer.
Character: bad

Pickpocket – seems like a regular person, but because he suffers from kleptomania, he's always stealing something.
Special Ability: steals a vote (he can only vote with one vote himself).
Character: good

Inattentive passenger – the most absent-minded person on the trolleybus – constantly loses or confuses things.
Special Feature: if he doesn't vote for execution, he dies himself.*
Special Ability: No
Character: good

*Meaning at least one vote)
