Kicking up envelopes during personal family gatherings was common back in the day, you just don't look in it until after the event is over or you leave early.

My conclusion is the same, that because Salvatore killed a made member in the family, the punishment would be Salvatore would serve his term in prison, while Aldo would never receive is button.

Dickie is made. Buddha is also made. That scene in front of the club where Dickie socked Buddha in front of Johnny Boy, is that Dickie could have asked for anything after Buddha insulted his goomah. A made man back in those days would not stand for it, and Johnny Boy would consider the matter settled as long as Buddha didn't make anymore insults, and Dickie would not put his hands on Buddha. Before that matter was settled, we know what happens during the moment.
