According to Ingroia "in an organization like the Mafia, a boss has to be one step above the others otherwise it all falls apart. It all depends on if he can manage consensus and if the others agree or rebel." Provenzano "guaranteed a measure of stability because he had the authority to quash internal disputes." According to Sergio Lari, deputy chief prosecutor of Palermo: "Either the directorate can choose a successor or we could again be in for a fiery time."
