I really dislike the seanchan. How can they enslave women simply because they can channel? And Tuon is a hypocrite! She can channel and still she enslaves others who can channel and make no move to get rid of damane. The seanchans are nuts!
The Seanchan were corrupted by the Shadow, I'm not sure they're scum. I don't like Tuon's defense of collaring channelers, but this has been their custom for (as far as we know) thousands of years. I think with more interaction with channelers on an even playing field, we've seen some of them change their views.
Yeah, The Seanchan's treatment of channelers are awful, but many parts of their culture are quite good. They are a rigid almost caste like society, but it does give their people stability. Just look at how they treat the people they conquered. The Taraboners are part of their military. The Tinkers are safe in their society. And yes, they have slavery, but slaves can actually raise up to high ranking positions and they have many rights. So, yeah, I have hope that with Min and Mat by her side, the Seanchan, with Tuon leading can be open for change and better treatment of channelers.
