However, if we don't execute him, and he's Mafia, then another move will be made on him at night with evidence against him, at worst, we'll just go in circles, and at best - if he's a Town member - he'll just remain in the table until tomorrow. The Mafia is unlikely to target him at night. So, I don't see much benefit for the town, rather, it's a disadvantage.

In general, out of 19 people, 9 voted! I think it's unrealistic for them to come to a consensus, and even more so to get 10 votes.
With this approach, the Mafia has won :D Tomorrow, nothing is likely to change in terms of activity. They'll just kill a couple more of those who spoke out, and with the silent ones - it's definitely a victory))
