You say that Vish might turn out to be not just a moneylender, but then the probability that you made the right decision regarding his execution decreases sharply. Isn't that right?
The probability that he is a witch is higher than the probability that Gur is a demon worshiper, and you can't give one group an advantage over the other, so executing him today is a higher priority.
That's all I have to say.
Logically, shouldn't we resurrect the townspeople just so that the Town can resist the Mafia? This would benefit the Templars, because if the Mafia wins, the Town loses, and consequently, the Templars...
