I thought Omerta was "the code of silence" or "Never Rat."
I get all my Italian knowledge from gangster flicks, so please educate me if omerta includes "revenge."

The code includes consequences for ratting. Just business.
Omerta is the Code of silence when dealing with the government. It literally means “manhood” and refers to the idea of a man dealing with his own problems without the help of an law-body, but the term has a also become synonymous with Mafia’s code of silence. Omerta is a very popular attitude in places of Southern Italy like Sicily, where the Mafia is strong.

It is more complex than silence. It is quietly taking matters into your own hands and settling things.
