Jimmy played the short game (ep 6 spoilers)
I think Jimmy let his emotions get the best of him. The lawyer had set McCall up to take the fall, and having him off the streets would be much better than having the lawyer around in terms of overall crime and violence. I got the impression that the lawyer, having bankrupted McCall with the money laundering skimming, was ready to retire to warmer climes. he just wanted to make sure McCall didn't come after him. But now we see McCall in the bar, back in power. Jimmy may not have made an enemy, but neither is he scot free as long as the crazy guy is breathing.
