1. Easily? Only a 50% chance of success. Add to that the fact that the Blacksmith is still alive and can block the Prophet.
2. Even if we recruit her, which we'll notice anyway, we can:
a) Execute her the very next day, before she has time to do anything;
b) Block her with the Blacksmith at night - again, she won't be able to do anything;
c) Kill her with the Hunter, because the Executioner status is also cursed.
In short, there's no point in recruiting her. But +1 city vote would be useful. And you think I'm a mafia member because I wanted to recruit her for myself, supposedly. :D
B) That's out of the question.
Regarding point C... Sure, and won't 4 mafia members eliminate the Hunter? No? The city doesn't know each other, but the Demons do, so it won't be difficult for them.
