Another thing that irks me is how so many people view Lando as some sort of traitor who needs to "redeem" himself somehow. He saved Leia, Chewie, and AN ENTIRE CITY FULL OF PEOPLE while risking the life of only one man, who he lead a team on a mission to save. It's not like he could have sacrificed himself to save the others. Vader knew Luke was coming and he knew Lukes friends were already there. Lando refusing to help would have only gotten more people killed and possibly a city destroyed. Even if Han died in the carbonite I don't see anything Lando could have done better and I see no need for any kind of redemption.
