I think it was a pro-town player that had to make a night-kill.
If somebody had to die, JohnGato the inactive was the best choice for a townie faction and the worst choice for any other faction.
However, he was going to be replaced. From a mafia perspective, one dead townie is as good as another.
Im going to have to disagree with you it was stated earlier that the mod we have usually wont replace unless it is a vital town role. So with the info we could pretty well say that he was important to the town or Mafia. Now we look at it further if it was important to the town the mafia now knew this; so with the info we can also say the mafia would of attacked without regard on JohnGato for the simple fact that he was an important role to the town.
