Sometimes I think that perhaps Lewis should have put more good Calormenes in his Narnia stories.  This would have helped to keep people from criticizing him for being prejudiced against the Calormenes as a race of people. But of course the people who have criticized him for that have greatly exaggerated his portrayal of them as the villains of the story. I think it probably would have been better to have more people like Emeth, but Lewis apparently thought one good Calormene was enough.

@narnian78 Well, two good Calormenes if you count Aravis!

But as I know I've said before, the Calormenes only appear as antagonists in two out of the seven books — they're actually not the big bad ultimate evil enemy of Narnia that some critics seem to think they are. If Lewis had spent more time on developing the world of Narnia in a broader sense, he might have given us a more nuanced view of the Calormenes and shown more aspects of their lives and culture, including, I hope, some more positive portrayals of individual people among them. But that kind of extensive worldbuilding is not what he ever set out to do with Narnia, so we're left to fill in the many gaps with our own imagination.

Aravis became better later in The Horse and His Boy, but she had to have Aslan teach her how to treat people properly and not be snobbish. Her arrogance was one of her faults. So she wasn’t completely good throughout the whole story, although she did a turnabout change with Aslan’s help. I still think good Calormenes were in the minority, and Lewis should probably have added some more of them to balance the good portrayal.

True, but nearly every "ultimately good" character in the Chronicles has flaws (sometimes worse ones than Aravis had) that they can't grow out of or leave behind without Aslan's help! Bit like real life, actually...

It would be boring to have completely perfect people in a story, and the Calormenes were no exception. But I think there could have been more of the good ones even if they were only partially good.  The Narnians had their flaws too, although they were sometimes portrayed as better than some of the Calormenes.  Tashbaan had some nasty people in the city in The Horse and His Boy.  I would hope most Calormenes were not like them.
