What is this rumor you keep talking about that the 'traditionalist' mafiosi don't kill women or children? They never say this. In Italy it is common understanding that if your wife/mother/son are in the way, or can be used for a bargaining tool, it will be. This is NOT a secret. It's common knowledge.
To be honest, I don't remember the exact sources where I read or heard this, but I didn't just make this up, that's for sure. They put quotes like this even in some movies. I remember only the case in which Totò Riina's hitmen killed the mafioso Vincenzo Graffagnino who was suspected to have killed a boy named Claudio Domino. Maybe this was a demonstration of their adherence to the old belief that mafiosi shouldn't kill children, I don't know.
But if you're going to be born into that life and/or choose to be in that life then do it right. A man that is in jail for life and under article 41-bis and doesn't talk, is a man of honor.
Were he truly a man of honor, he wouldn't have done those things he ended up in jail for. Not talking means nothing from a moral point of view.
But anyway, I am not trying to start an argument or provoke you. I just don't understand what's your personal point of of view on that concept of mafia honor.
