Logical decision of Mucci not wanting to step in as leader of the old Rizzuto group. History has shown that he'll be marked and he knows that better than anyone. Not for nothing he's one of the last of the Mohicans. However, it seems that even the Rizzuto family have lost faith in Stefano Sollecito and that he's becoming increasingly isolated. Or perhaps he's now too ill to lead. In any case, it must suck to be him right now.
The intriguing question remains of who is behind these attacks. I'm suprised that so far not even a hint is given.
