Lando Calrissian could have been the most interesting Star Wars character. When we first meet Lando, we are lead to believe he's shady by the way in which Han Solo regards him warily. Indeed, it turns out that Lando cuts a deal with Darth Vader and his troops right before Leia, Han, Chewbacca and Luke arrive, turning over the good guys to Darth. As he tells his friends, he had no choice, because Vader arrived before them. Judging by the protagonists' anger toward Lando for his actions (including a bit of strangulation from Chewie), we are led to believe that Lando acted unscrupulously. And when Lando helps out the good guys, we feel the joy of redemption. Scoundrel turned good guy!
The problem with this account, of course, is that Lando was coerced into cooperating with the Empire. The Empire would surely have slashed and burned Cloud City had he not. Aristotle said (roughly) that moral responsibility involves being both aware of one's actions and doing them voluntarily. In Aristotelian thinking, Lando didn't act voluntarily; rather, he acted under duress. And how many of us would not have acted the same way, to save our families, our country, our planet?
What would have been a more interesting approach to Lando would have been to make his actions be voluntary. Perhaps Lando thinks he can profit by aligning himself with the Empire. Under this set of circumstances, his moral conversion would have had more force. And perhaps the conversation would have been only temporary--perhaps he's constantly pulled by self-interest into doing less-than-savory things. But that's the essence of the Star Wars saga--there are these two archetypes--good and evil--and people are in one camp or the other. Several characters changes camps, but nobody really oscillates between them or inhabits some middle ground.
In our world, we inhabit the middle ground. Sometimes we do the right thing, sometimes we don't. Quite often, we don't even really pay attention when our hearts are telling us that some action or another doesn't sit quite right. Paradoxically, sometimes those closest to us bear the brunt of our mistreatment, because we may be able to get away with a little more. When I find myself caught in some variety of subterfuge or another, I think of it as my Lando mode. If Lando had been written with a bit more nuance, he would have been the link for all of us imperfect beings into the Star Wars mythology. We're all a bit Lando, after all, aren't we?
