This isn't the first time that a father or brother was hit and the other family members stayed active within the family with no retaliation. It was a great point earlier that Chickie hit a boss when he plotted with Casella. He got what was coming to him. For the Narducci's to go after Salvie or Scarfo for that matter would be instant death for them as low-level soldier or associates. Take Bruno Indelicato, he never retaliated against Massino or anyone else involved in sonny reds death... Or Mikey scars brother got whacked and when Castellano told him it wasn't his business and don't retaliate, he didn't. It's part of the life, probably THE WORST part of the life, but a part none the less. And if you were a gangster through and through, you're gonna roll with it.
