The risk is three-fold if we lynch Hatmoza and he's telling the truth.

1) We lose the chance to recruit a powerful ally (Kratos.)
2) We lynch a townie for the mafia.
3) We waste a lynch.

again, its incredibly obvious that Zeus is in the game and was targetted by the Mafia last night, why people dont want to believe this when it basically says it in the Day Start narration is beyond me, perhaps they are mafia and hope that this makes the doctor/protector ignore the possibility of there being a Zeus, so doesnt try and protect him?

Hatmoza im not sure about, his role-claim sounds plausable, but im not convinced of his alignment..

Exactly. Zeus is a way too important character to miss in the game, saying that he doesn't play is like God of War without Kratos.

As for your first one, thats if he is telling the truth, and while a vigilante can be useful they can still be extremely dangerous for the town as well.  Since at night they are still just randomly picking targets. 

difference between daytime and nightime? does his kill appear in the day?

who said silver got killed? please read again...

It seems incredibly unlikely to me.
If Hatmoza was just making this all up he'd have to:

1) Bet on Kratos being the serial killer.
2) Bet on nobody calling out his name-claim.
3) Bet on not being investigated by the cop or tracker at all for as long as he lives.

And for what? All Hatmoza gets from his early role-claim is lots of attention. Stefl was a very different case as he gained a lot of power during the day with his investigations.

Here's the bottom line:
Hatmoza's cards are flat out on the table now: if he's lying we'll be sure to catch him out soon.

Right now there is nothing to prove that he is not telling the truth.

One could say the same thing about Shao Khan from Mortal Kombat

The Daytime Vigilante kills during the day, with his identity and action openly exposed when it happens.  The game where Words of Wisdom moderated is a good example of how that works.

Regarding Silver: "Silver and I believe appolo was killed by patapon" is a horribly disjointed sentence, especially if you're trying to connect Silver to the clause before the ellipses.  I don't want to go all Grammar Police on you, but what you wrote apparently doesn't mean what you meant, since what you wrote means "Silver and Appolo got killed by patapon." 

So, what did you mean?

1) Again, that was a logical assumption to make: hatmoza even mocked Khuutra for briefly challenging that premise.

2) Who said he isn't Athena?  But then again, who's to say where Athena is aligned?  We've heard rumblings already that Athena's not a goody two-shoes in the God Of War series.  We've also had it hinted that she wasn't a friend of Zeus, either.

3) That is the only risk he would take, and for what it's worth I think hatmoza's sufficiently high-profile that he would probably be investigated at some point anyways.  And of course we can all agree that Khuutra (Mafia) was also likely to be investigated early on; deflecting the inevitable investigation from a teammate would be a viable strategy.  Moreover, he's certainly doing quite a bit to try and discredit anyone who challenges his claims: perhaps he would figure that he can stave off an investigation by being obviously pro-town: the cop(s) certainly have enough folks to look into as it is.

No, if hatmoza's anti-town there's a rational motive behind his actions.

How do you figure, especially now that a cop has died?  How is his capture inevitable, especially if we accept his statements without reserve?

There's no smoking gun, but there's certainly cause for concern. 

1) He was quick to get defensive when challenged,

2) He's taken to accusing anyone who suspects him,

3) After his initial post he's made little effort to convince Kratos to expose himself (do you realize you've done just as much, if not more, for that cause than he has?),

4) He (a long-time Mafia veteran) committed the faux pas of posting long after night had fallen simply to reiterate that 'he will find Kratos' (why does he feel the need to reiterate this? The only reason I can see is to bolster his own credibility),

5) His story this morning requires us to believe that Kantor trusted him enough to NOT use his lie detecting ability on hatmoza's claimed role,

6) Kantor gained information to narrow Kratos to two people AND tell this information to Hatmoza, all in one night (i.e. Kantor can take two separate night actions in one night),

7) He's a psychiatrist who is told that his possible patient will become a vigilante: judging from the last game with a psychiatrist, the psychiatrist is not explicitly told what will happen when he finds his target,

8) He FoS'd Khuutra (Mafia), despite Khuutra doing the opposite of what he listed as being suspicious behavior.

I'm eager to hear his answer to your questions.

Exactly. Zeus is a way too important character to miss in the game, saying that he doesn't play is like God of War without Kratos.

@Dtewi:

Why shouldn't he reveal that Zeus was attacked? Revealing the role =/= revealing who has the role. In fact, 3ever even gave away another role when talking about Zeus' attack, the Sisters of Fate.

Ok: but I think it's more of a risk to lynch him than anyone else since he's revealed so much already.

So far the only valid reason to lynch Hatmoza is the elaborate theory that he's a mafia serial killer recruiter who thought it would be a great idea to announce his role to the town immediately and hope he didn't get investigated by the cop.

Also: if Hatmoza is telling the truth and we lynch him we're theoretically losing two townies instead of one.
