Should Robb have executed Jaime?

Then why didn't he just agree to exchange Jaime for Sansa and Arya and go back to Winterfell?

Because he was King (and he liked it) and he was under pressures of the norther Lords... he was very young and in a very difficult position.

Yet Tyrion had no idea Jaime was actually being released at the time Catelyn freed him. It was Robb who was in negations with Tyrion not Catelyn. Robb never wanted Jaime released and sent men to bring him back as his prisoner.  In the North's and Riverland's minds Jaime was an escaped prisoner. That's why Jaime did not freely travel back to King's Landing and ended up losing his hand. Also in that time Sansa was married off and became a part of another family.  That was the huge flaw in Catelyn plan that she didn't she in her grieve. How Robb would react and how the Lannisters would react to Robb hunting Jaime down after he was "released." I don't think Cersei, Tyrion nor Tywin would be happy that Jaime came back missing his sword hand. To them it would seem that Jaime barely escaped with his life. That's not exactly how a hostage exchange works.

Tyrion knew Cat, not Robb; even without communicating directly they followed the same logical thread. Also Robb sent him laughable peace terms. But yes it was a risky move, freeing jaime. She was very desperate.
