Chuck might've been proud of his brother then, but his final words to Jimmy were "you've never mattered all that much to me." This stinging farewell supersedes whatever niceties might've been written in Chuck's posthumous letter.
In a flash, Chuck saves Thomas' life by diving in front of the knife. As Thomas cradles Chuck in his arms, he wishes that Gally had attacked anyone but Chuck. Before dying, Chuck's last words are “Find my mom. Tell her…” Thomas feels a dark and terrible rage swell inside of him as Chuck dies.
And by the way, she wants to set the record straight: “Kim did not write Chuck's letter.” Saul's writers confirmed to her that Jimmy's late brother really did write the letter Jimmy received after his death. It wasn't her character's invention, as some fans have theorized.
Kim wrote the letter
She wrote a new one trying to say nice things that maybe would make Jimmy grieve in a normal way. When Jimmy didn't seem to care about the letter, Kim was racked with guilt and that's why she wound up crying.
Of course Jimmy is upset by the death of his brother, and he knows that he is partially to blame for his demise. He knows deep down that Chuck's ailment and eventual death has to do with his actions. But that truth is too painful for Jimmy to face. Chuck was a nasty older brother in Jimmy's eyes.
Likewise, Chuck likely felt regret in the way he treated Jimmy and realized that if he had not been so antagonistic to his brother in the past, his present would be much different.
Jimmy shows an absolute love for his older brother. After all, it was Chuck who helped Jimmy get out of trouble back in Chicago — when Jimmy defecated on top of a car in front of children, Chuck represented him as his lawyer. It was also Chuck who hired Jimmy to work at HHM's mailroom.
Dear Jimmy, I have left many things unsaid in our relationship through the years. Rather than allow these unspoken thoughts to die with me, I've chosen to record them here for you. I hope you will take my words in the spirit in which they are intended.
Despite Kim and Jimmy's unconditional love for each other, Kim left him and Albuquerque after one of their schemes went horribly wrong, causing her to believe that they were bad for everyone around them. She subsequently retired permanently from her law career, and divorced Jimmy later that year.
Jimmy's cold reaction while reading out Chuck's letter was also a vital step in his gradual Saul Goodman transformation. Jimmy even refused to properly acknowledge his brother's death or consider that his actions might've pushed Chuck to suicide.
With Kim's encouragement, Jimmy started a solo practice after HHM decided against hiring him as an associate. During the period leading up to the events of Better Call Saul, Kim and Jimmy are shown to have developed a close personal relationship, which eventually turns romantic.
Chuck leaves most of his estate to his ex-wife, with only a $5,000 bequest to Jimmy, which is just enough to prevent him from contesting the will. When Kim picks up Jimmy's inheritance check, Howard gives her a letter Chuck wrote to Jimmy.
Clair, the fake name they used during their tequila con job on Ken back in season two. It turns out that Jimmy actually was yelling at Kim during the phone call we got a glimpse of last week because she told him he should turn himself in and he challenged her to consider why she hadn't confessed herself.
He was angry because of what Chuck said to him. He was angry with himself for allowing Chuck to affect him. He was mostly angry that the brother he wanted, the brother he thought he had, never truly existed, he wasted his life catering to his needs, always trying to please Chuck.
Trivia. During the Better Call Saul Insider Podcast of the episode "Chicanery", it was revealed that Rebecca and Chuck are divorced, or at least separated, since 1998.
Thomas realizes that Chuck was a personal symbol for the possibility of returning to a normal life. Now that Chuck has died, Thomas feels that the life that lies ahead of him will be full of misery and sorrow. After the woman says that's all things happen for a purpose, there is shouting and commotion from the doorway.
Type of Villain
Kimberly "Kim" Wexler is the tritagonist of the 2015 AMC crime drama Better Call Saul, the prequel to Breaking Bad. She serves as the tritagonist of Seasons 1 and 2, a major character in Season 3, one of the two tritagonists (alongside Nacho Varga) of Seasons 4 and 5, and the deuteragonist of Season 6.
One of the subplots of the show follows Chuck's obsessive compulsive order (OCD), a mental illness where people suffer from intrusive thoughts and compulsions.
Antisocial personality disorder
The arc of his character is carefully constructed to resist moralizing.
He believes that Jimmy with a law degree is dangerous and an insult to the legal profession, and rationalizes his conniving and betrayal as serving the greater good. Chuck later hatches a scheme to have his brother disbarred.
After confessing the full truth of Howard Hamlin's death to the district attorney's office and paying the same courtesy to Cheryl (Howard's widow) Kim breaks down crying on the bus. Her public outburst represents the accumulated sadness, grief and guilt she suppressed for six years while living in Florida.
While Chuck's condition is real in the sense that EHS is inspired by real life, it's certainly not real in the traditional sense. Like anti-vaccination and climate change being a hoax, EHS is the result of false information spreading and seizing advantage of those with existing psychological conditions.
Don Eduardo "Lalo" Salamanca is a major antagonist in the Breaking Bad franchise, serving as one of the two main antagonists (alongside Chuck McGill) of Better Call Saul and a posthumous antagonist in Breaking Bad.
Ultimately, things reached a point where Chuck's final words to Jimmy were, "The truth is you've never mattered all that much to me." So, why didn't Jimmy solve the situation by telling this to Kim?
Perhaps Chuck began to complain to Rebecca more and more about Jimmy, chastising her for enjoying his company as much as she seems to. Perhaps Rebecca began to feel uncomfortable caught in this brotherly feud, and their relationship spiraled downwards as a result.
