Why did it never cross Castellano's mind to whack Dellacroce? It would have surely curtailed a lot of problems down the line. Dellacroce showed no deference or respect to Castellano. No other boss would have tolerated it.

Gotti and Ruggiero were following Castellano's lead too. The reason they were so volatile and confident in taking out Castellano is because they were following Dellacroce's lead.

And so what if Castellano was banging his maid. Gotti and Dellacroce had bigger skeletons in their domestic closets!

I invoke my right under the 5th amendment of the United States constitution and decline to answer the question.
