Not necessarily. Say for the sake of reasoning that:
Innocents: Holby and Kath
Wolves: Formendacil and Fordim
Cobbler: Boro
Now the point of the Cobbler is to want to die yes? So say the two wolves voted for one innocent each (since they have a choice of three it's possible) and the two innocents vote for a wolf each and the Cobbler votes for himself - 5 way lynch!
But its unlikely to happen
