What happens in Hamilton affects the Luppino's. It is common sense that your business associates would be consulted.
and why he didn't go after the Violi sons was obviously a change of heart for precisely the same reasons you gave.
It would be better for business perhaps (hence why Montagna consulted so many people), but if Buffalo decided to kill Papalia (or sanction his murder) the Luppinos could do nothing else than go along with it since it would be a family matter.
Yes, there is nothing the Luppino's can do, but on the other hand the Luppino's can decide to form an alliance with other New York families that will gain their respect. This is why common sense prevails.
