What are some of the inner conflicts the characters experience in Unwind?

Unwind is flush with external conflicts; however, it is the story's internal conflicts that really resonate with readers. Each main character does struggle with individual internal conflicts throughout the book, but in general the main characters do struggle with the same internal conflict too. Connor, Risa, and Lev are all Unwinds. Their parents have decided for one reason or another that their body parts are worth more than the person that they are now.
Connor struggles deeply throughout the entire series with the knowledge that his parents intentionally signed his unwind papers because they thought he wasn't worth the trouble of raising further. His girlfriend didn't even want to come with him. Connor struggles with feeling like nobody wants him. Risa helps with that as does the Graveyard.
Risa struggles with the same feelings of being unwanted. Her case is a little bit different. She doesn't know who her parents are; however, the StaHo decided to make more room for new children, and that means kids like Risa need to be unwound. They aren't worth keeping around anymore. Risa will also struggle internally with her feelings for Connor.
Lev struggles internally more and more as the story continues. Lev is a tithe, and he has been brainwashed to believe that letting himself be unwound is somehow God honoring. As the story progresses, Lev comes to see the error in that thinking, and he really begins to despise his family. He doesn't understand how they could do that to him. Lev becomes so bitter against the entire tithing process and unwinding lie that he turns himself into a clapper.
