[08 Jan 2016] Mafia - The Archive

[STM1993]

^Cop was killed because you chose to save yourself. Sure there was a risk but you should have saved him anyway. As far as I recall, you were never targeted. Every single night a person was killed.

To be fair,
Night 0 - you have no information about anything or anyone, and it would be silly for a power role like Doctor to die even before the game can get going. If you can at least survive, even if Mafia knows who you are, you have a shot at saving someone else later on.
Night 1 - Rhino has taken the risky option of saying he's the cop, and he did get a Mafia mfc lynched. If I were Mafia I'd think this little incident would cause the doctor to protect the cop, and attacking Rhino right then would only prove to the doctor that Rhino can be trusted. Mafia can actually target themselves if they so desire, but that is an extremely improbable move given how risky it is; you'd basically be having the Mafia kill themselves TWICE, leaving only one guy behind and that is a very bad idea for Mafia.
Night 2 - Since no one stepped forward, Rhino is pretty much confirmed Cop, and the public sentiment is that Rhino would remain protected. Darl gambled on that sentiment and protected himself in case Mafia decided to try and aim for the doctor instead, but Mafia also gambled on taking a shot at killing Rhino and succeeded.

After that night, it becomes very hard for the doctor to really know who to save (especially when you look at the players still in the game); the odds of successfully saving some other guy at night is very low, so its best for the doctor to just save himself; at least he knows he himself is definitely townie. It should also be noted that Mafia side didn't think Darl was the doctor, but it is not unreasonable in Darl's shoes to think he would be killed.

Of course, round is over and hindsight is 20/20, so I would suggest not to continue to criticize on what players could have done.
