On the setup screen, Neutral Killing role descriptions say "An XXX wins when he is the last man alive." In game, Neutral Killing cards have the objectives "Be the last person left alive." However, these descriptions are false. Neutral Killing roles can win with Survivors, Amnesiacs, Witches, Auditors, and Judges. I think it would be more clear and accurate if the objectives were the same as the current Mafia/Triad objectives: "Kill off the Town and everyone else who would oppose you."
These misleading role objectives can affect gameplay. I've attached a replay in which there was confusion about whether a Survivor could win with a Serial Killer.
