Italian Mafia never respected that rule.Sicilians,Calabrians or Napolitan doesn't matter,no one respect that rule.
There are no honor between criminals.
Maybe in the last 1800 and the early 1900 when the mafias was only a rural thing maybe and repeat maybe the don't kill women and children was respect.
The only rules that all criminals respect is to kill the pedophiles; even the worst criminals if rape a child can be killed so in the prisons the pedophiles stay in separate wings, and in some cases are killed despite it.
