Vito and Carmela was a great team Granted times were different and Carmela was a traditional wife of that time

I do believe if not for Carmela, Vito's Rise and Rise may not have been perhaps as smooth or not to this extent, keeping in mind Vito became a crime boss after their marriage

We hardly see Vito being a family man It seems Vito took care of the crime family and Carmela the blood family without any conflicts

Carmela was culpable too Carmela knew what her husband’s business was knew her rich, privileged life was funded by tainted money from other people's murder, misery and blood but happily enjoyed the spoils of the blood money seemingly no qualms
