Are killing roles only classes that has a primary ability to kill?
(Vigilante, mafiaso, serial killer)
Are killing roles also classes that indirectly kill, such as body guards?
(example: I put random town EXCLUDES KILLING TYPES. Will I have bodyguards in the game?)
What happens when you allow a random power role, but exclude killing roles? How about exclude power roles but allow killing roles? Does the power role "trump" the killing role? (serial killer, for example, if I allow power but exclude killing, will serial killers exist? If I exclude power but include killing, will serial killers exist?)
