Al D'Arco explained it best - while it doesn't hurt if a guy has killed for the family, the main thing is a guy being willing to kill for the family. That's what they ask of the inductee in the ceremony. And, as George Freselone said, if a guy is a good earner the family doesn't care if he's ever seen a gun. But D'Arco said they all know the call could come one day to participate in a murder.
