Fk almost made a big mistake.
Not really. Villagers would know (or suspect, anyway) that I'm not a wolf. Wolves would know for sure, so they would definitely try to influence a vote my way. If there is a general consensus towards voting to kill me, then obviously I am not the right target.
In the beginning, I cannot know which side I am actually on, so, how can I choose which side to fight for? I can't choose village or Wolf until I know; define 'winning' in that context and you begin to see the headache :D
Edit: basically, the drunk can do whatever the hell he wants to until he learns what role he is. Page 1 of this thread:
[the drunk] doesn't know what role that is. It is not uncommon for the drunk to lie about his role until he can decipher which side he is actually on.
