Everyone thinks that jimmy’s breaking point into becoming saul was the revelation of chuck’s betrayal and being forced to believe that he would always be slippin jimmy, but i think it might be deeper than that. I think it’s because, through said betrayal, jimmy realized chuck, who he aspired to be, was just as bad as he was.
The difference is between the letter of the law and the spirit of the law. Chuck takes the law to be sacred, such that any violation of it is immoral. But Chuck, dogmatic and legalistic, failed to see that the letter has always been lesser than the spirit— that doing the right thing is more important than the law.
Let’s say Chuck was right about Jimmy— that he couldn’t be trusted with the sandpiper case. This is a legitimate claim. Jimmy has constantly bent and cheated the rules. On such a big case, could Jimmy be trusted to not bend the rules and take shortcuts? Especially since the stakes are so high and concern so many innocents. Chuck was right to not take that chance with Jimmy. However, the problem isn’t that Chuck took Jimmy off the case, but the way he did so.
The minute the sandpiper case became too important for Jimmy to screw up, Chuck should have given it to Jimmy straightforwardly and took him off the case. But what did Chuck do instead? He lied and deceived Jimmy, making Howard to the dirty work to pull the rug from under Jimmy. If it was really about Jimmy’s rule bending, then why not say so? Because Chuck has only ever cared about the letter of the law, not the spirit of it. Chuck only ever cared about keeping his hands clean, not realized it made his heart dirty. Even though Chuck never broke any laws, he still cheated and deceived Jimmy, doing the exact same thing he disdained Jimmy for.
This was what sent Jimmy over the edge. Chuck was Jimmy’s role model, his vision of who he has always struggled to be. But all Jimmy saw were Chuck’s clean hands, failing to see the black heart within. The revelation breaks Jimmy, revealing to him that the person he has always tried to be was just as bad as Slippin Jimmy.
Chuck was Jimmy’s lighthouse, bringing light to the dark and showing Jimmy the way, only for the light to be revealed as a lie, casting Jimmy back into impenetrable darkness. If there is no light illuminating the way, then one can only embrace wandering off into the dark.
Jimmy: "I thought you were proud of me."
