I've gone by them being able to do both. It's of the school of thought for this particular game that views the mafia kill as a collective action attributed to the entire group, not a specific action performed by one of them.
Otherwise as soon as the town gets either mafia member it severely crippes them. Better to make it so they only lose the ability to RB if they lose the RB I think.
