That's what I meant by saying Jimmy provided Chuck with a lot of cover, with which to dress up his real motivations. Jimmy was making a real effort to go straight. He put in his time in the mailroom, he did correspondence courses with likely the only "law school" he could get into, and whatever he did it was sufficient to impress Howard enough to offer him a job with HHM, but Chuck torpedoed that, and we saw what Chuck's real motivations were when he broke down on the stand in that hearing and he went off big time about his parents' "precious Jimmy."
The writers deliberately had Kim accuse Chuck of being Jimmy's "creator."
Just because you can make a persuasive case that Slippin' Jimmy with a law degree could have potential to go badly, that doesn't mean that's the real underlying motive, and in Chuck's case it wasn't, and that was made plain to us. The juxtaposition was interesting. At heart, Jimmy wasn't really a bad guy, but Chuck was.
