Is this typical CE victim blaming and siding with villains again.
Jimmy was bad news. Chuck knew it. He knew Jimmy was gonna do something terrible. And hey Jimmy did.
Yes, Chuck is characterized as unstable and unreliable, but he is also the only one who knows Jimmy, knows his patterns, and knows he will never be able to be fixed.
But Jimmy did get fixed in the end by taking responsibility for his role in the Heisenberg empire. I dont know if its something he wouldve done for Chuck if he didnt turn on him, but he did do it for Kim.
