Why did Carlo flip sides?

Carlo Gervasi turned state informant due to him wanting to save his son, who had been arrested by the FBI on drug dealing charges.

The Sopranos is still one of the most cinematically and academically acclaimed television series to date. Premiering in 1999, the show would enjoy a six-season run, with the last season of the series airing in 2007. The premise of the show as shared by IMDb reads, “New Jersey mob boss Tony Soprano deals with personal and professional issues in his home and business life that affect his mental state, leading him to seek professional psychiatric counseling.”

While the series might be touted as one of the best television series in history, its finale faced what is recognised as the finale season curse. This refers to hit shows with an avid following that fail to appease viewers due to the way in which the series is concluded. The Sopranos was faced with a similar fate, especially due to the decision to leave it with an open-ended conclusion, which left more questions than answers.

One such contention with the plot of the series finale episode, is the matter of why Carlo Gervasi, who was lead character, Tony’s caporegime decided to turn into an FBI informant. The episode first saw the arrest of Gervasi’s son, Jason, who was arrested for drug dealing. Suspicions that Gervasi might have turned FBI informant arose after he failed to show up for an important meeting. Initially, Tony’s suspicions at the time were that there was an informant in their midst – a fact which his attorney first confirmed.

However, there was no proof of who it was at the time. Nonetheless, as the final episode was about to conclude, his attorney confirmed that Gervasi was the FBI informant. The fact that he was attempting to save his son was attributed as the reason for his betrayal. However, a definite answer to this question will never be known, seeing that it has been over 14 years since the finale and the question has still not been answered.
