Yeah, I have no sympathy for Chuck at all. And hell, what Jimmy did to Chuck -- while far more illegal than anything Chuck has done -- pales next to the things Chuck did him on a personal level. I mean, in the end all Jimmy really did was professionally embarrass Chuck and his firm and cost them a client. Compare that to everything Chuck has done to not only Jimmy but Kim as well.
Sure, neither of them are saints, but Chuck is by far the worst of the two. The amount of hate he has towards his brother has been palpable for a long time, going back as far as the flashback to the dinner they had with Chuck's wife.
So, yeah. Zero sympathy for Chuck, especially since instead of just accepting that he got his comeuppance, he went out to try and gather evidence to presumably get his brother disbarred and/or thrown in jail for dong what -- despite what the law says -- was far and away less harmful than pretty much anything he did to his brother.
The sad part is that you almost know for a fact that Jimmy is going to expose himself because of his compassion and blind love for his brother, thus allowing Chuck to win yet again.
Fuck Chuck.
