Similar to Nicolo Sr, Victor or anyone else who will take on leadership position. It was more than likely a organization decision, probably involved talks in Sicily/Southern Italy, South America, and everywhere else the Rizzuto does/did business.

The West Coast of Sicily is very influential, and the link to Palermo and Reggio, was evident in the bridge deal to Messina, that Rizzuto was part of that was worth billions of dollars. I think Rizzuto was convicted in Abenstia. Not to mention Nicolo Sr links to Milano, and everything that Milan represents.

Although Victor Rizzuto is gone, the system that produced him remains, I assume whatever decision have been made, it will have taken a similar process to make them, they are typically made in and for blood.
