Tony, the assumption that Carlo Gambino, being a more respected and threatening boss than Costello, would have been avenged had he been disrespected by Galante in the manner Costello was, is inconsistent with the fact that Galante insulted Carlo Gambino and Carlo was not able to have Galante removed, despite being hailed as boss of bosses.

Regardless to what Carlo's supporters would have done with Galante had Galante disrespected Carlo the way Costello was, the fact of the matter is that Carlo didn't have the power to remove Galante right away while he (Carlo) was actually in power.
