I find a lot of things wrong with your reasoning.
First of all, over half of us voted for alive. It's not really telling at all if we voted for him, except it *probably* means the ones who voted for him don't include the other mason, except even that isn't a sure thing- i.e. alive was a mason and voted for himself. It's not telling in and of itself, it's just another data point.
As far as monkey voting for you after you voted for him, that isn't unusual. It's very common for an innocent to counter-vote against the first person to vote for them. Except I wasn't the first person to vote for him...either day.
As far as the mason outing himself, I disagree. The evils are guaranteed a goodie kill if they want one, by killing the outed king prince. The real goal for them, of course, is to find the seer, so they must choose between going for the sure-good prince, or taking a risk and hoping to find the seer. If you add a known mason into the equation they must choose between killing the prince & mason in the next two turns, or ignoring them and trying for the seer. If the evils choose to go for the seer, it doesn't help them that the mason is outed, because they won't eat him anyway. On the other hand, if the evils fo want to kill the prince & mason first before moving on to random kills in hopes of finding the seer, that means our seer gets 2 more turns unmolested to get some real quality information.
IMO it's win-win for the village. Either the wolves let our seer work and get outed, or they don't get any benefit at all out of knowing the identity of the mason. The village on the other hand has a known good player who they can trust and that increases the chances of picking a good lynch.
You are ignoring something very important here, and I believe you are doing it purposefully. Outing the mason gives the sorcerer one less person to investigate, which makes it that much easier for him/her to find the seer, who can then be eliminated by the wolves or the sorcerer, if they are the wolf at that point as well. And then we're flying blind. In short, it's not a solid play for team good.
I'm kinda thinking you are acting a bit like the cultist would- just giving generally bad advice since you don't want the village to win, but not picking any specific lynch target since you don't know who your fellow evil team members are. Hmm. I'm going to leave my lynch vote as-is though, I have a funny feeling about juju.
