I think Ralphie's fate was sealed from the moment he killed the stripper and Tony was just looking for an excuse. I think at that moment anything Ralphie did or said would have just been seized upon as justification. Even if he had done the human equivalent of a dog rolling on its back and baring its neck in submission, he was done.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
