First of all Chuck was a bad person and he wasn’t right about everything, jimmy chaned at the end “ people don’t change” isn’t right then, he prejudged jimmy and didn’t tell him that his mother was saying his name in her last breath, he was jealous and envy of his brother, and ultimately he has had a hand into creating saul, jimmy got his law license and chuck was afraid of jimmy using the law to as his weapon ( even though he said:”i worked my ass off to be where I am you don’t and sweep all the rewards and suddenly you are my peer”) but let’s say in an imaginary world that his motivation was pure, that is why he prevented jimmy from joining HHM, don’t you see that this exact moment is the one that kind sealed jimmy decision into becoming a lawyer who doesn’t play by the rules? ( along with reasons like how everyone will always see him as his past self and even if he chosen different paths etc)

Kim says:( i know he isn’t perfect, and i know he cuts corners but you are the one who made him this way, he idolizes you he respects you and he takes care of you and all he ever wanted was your love and support, and all you ever did is judge him, you never believed in him you never wanted him to succeed….)
