The faux pas of Tony punching Ralphie after he kills Tracee feels a bit contrived in retrospect
I'm aware about the general Mafia rules about laying hands on a Made guy, but it kind of feels a bit hard to take seriously when the show is full of examples of presumably Made Men attacking each other, insulting each other and trading punches often with very little provocation, thinking of things like Tony smacking around Mikey Palmice when he was feuding with Junior or everybody jumping on Christopher at the intervention and him punching back. Additionally, like, I just find it hard to believe that with the Mafia of the early 2000s, especially as its portrayed in the show, that any of these guys are still so deadset and loyal to the rules that this would genuinely become an issue, and on top of that further, Tony is the acting boss, Ralphie isn't even a Capo at this point, he's tenderized people's faces for far less.
But even putting that aside, Ralph's actions were so outrageous even purely from a cold business perspective where Tracee being an actual human being is ignored that it demands recompense. A murder committed in one of Tony's public facing businesses with no attempts made to hide the body and it clearly being visible for anyone to find (remember when they all go outside to inspect the scene and someone almost drives up asking if the place is open?) with it being very obvious who the prime suspect is would be catastrophic if this went public and a police investigation began, it could seriously damage everything that Tony has built and probably destroy this business and a lot of the people associated with it, especially Silvio and Ralphie himself. Ralphie doesn't even go to the others to ask them to help clean up things, he just pretends that she slipped and that's the extent of what he seems to want to do, if they hadn't went outside and checked for themselves and left it till the morning, anybody could find the body lying there in broad daylight and it would be a complete disaster. I know people joke about him "disrespecting the bing" but he really did, it feels like such a major infraction he probably even should have gotten clipped for it. For all they know one of the other girls might crack and end up talking to the police, and its another body to bury and death to explain that the FBI probably added to the file to use later. They were extremely lucky that things didn't get much worse, that there wasn't a witness or much further follow up seemingly, and it clearly showed Ralphie to be at minimum a violent maniac who acts without any thought to the potential consequences no matter how ruinous this could be to Tony's entire operation, he earned a lot more than a clock to jaw for that.
