How did Armand develop as a character over time in the story?

Armand has difficulty in accepting the realities of race. All his life, he was the master, the dominant being. But after learning about his mother, would he deny himself what he denied others? It may be the case that if Armand truly believed in the racialized hierarchy of his day, in the inferiority of black people, and in the supremacy and superiority of white people, he (ironically) would sell himself into slavery or some kind of bondage. On the other hand, the psychological impact of this newfound information may lead him - as he is quite a religious individual - to repent and atone for his sins and to possibly go looking for Desiree and their child. However, this is completely left to the reader's imagination. What is clear is that Armand slowly comes to terms with his child's skin tone, which he sees as God's (apparent) unjust punishment. He denies that he did anything wrong at all to deserve this. At the end, he comes to realize that he was the sinner all along.
