Well then I would vote for you, because you are using the number 1 way of losing, should you be a citizen. If you accuse somebody of being mafia, because they accuse someone else of being mafia, because they are trying to figure out who it might be. This is why Lucario was always killed. People would use stupid tactics to find somebody to kill. By the way, if you think that it is improbable for such to happen, think again. The chance is 1 in 15 because such events are imdependant.
Here's the reason why you can't vote no-kill:
If you don't then the citizen to mafia ratio becomes 4 to 10. The sherif has a 4 out of 10 chance of getting a mafia member. In the next round, he has a 4 out of 9, but the numbers drop even more. Should he find someone, he can't reveal himself. If you vote to kill someone, then you have it drop to either 4 vs. 10 or 3 vs. 11. In the night, it becomes either, 4 vs. 9 or 3 vs. 10. However, the sherif isn't revealed.
By the way, do you honestly think that somebody who isn't in the mafia, would say that they are the Godfather? Only if he was frustrated would he post that.
