A good story should have a character arc where the protagonist learns something, but you have to set up that he is struggling with a conflict, how he comes to a decision, and the consequences thereof. Saul Goodman was a con artist who couldn't stop himself. Even when he was in hiding, he couldn't stop himself from the thrill of running a scam. But then at the end, out of the fucking blue, he decides to completely change his character with no explanation other than he decided to simp for some chick who left him a decade ago.
The turn doesn't add up. It violates Checkov's gun law--if you set it up you have to use it and if you use it you have to have set it up.
