It seems like the Mafia has 5 votes, while the town, including the serial killer, has 6.
There's also the possibility of an unrevealed theft, which could make things even more serious.

Wait, if the Robot has joined the Mafia, does that mean Red Bear is one of them? Then why isn't anyone executing him?
Because it's not certain that Red Bear is one of them, and even if he is, it's still better to find and execute Windows first, and then deal with Red Bear later.
