I agree with Blonde. That's the way the mafia works. Funzi Tieri also encoured members from Angelo Bruno's family to turn against their boss. But after Bruno was killed Funzi ordered the death of the same men he had encoured to kill Bruno, because they had shown to be disloyal. A same thing also happened with Bonanno zip Cesare Bonventre who had conspired with others to kill Carmine Galante, but was eventually wacked himself as he was seen as a liability.
