It isn't quite as simple as that: Macdonald considered Marmont had made an error of judgement and remained friendly with him, though Caulaincourt was harder on him - it is quite interesting to compare the two accounts of events.
Both Caulaincourt and Macdonald were really furious with Ney who ratted by sending in his adhesion to the provisional government without telling his colleagues (before going back to Paris as a commissioner), yet this never seems to be held against Ney.
According to the Munro Price book (The End of Glory) Caulaincourt tried to engineer military defeat in order to get Napoleon to negotiate - Caulaincourt was also a friend and regular correspondant of Talleyrand's. Are you going to take Caulaincourt off your 'approved' list?
People are complicated.
