I believe it can be argued whether or not this play exemplifies moral criticism. In my opinion, the best example that adheres to piety and virtue is the main cause of one of the characters not wanting to go to war. His father was lynched, and he blames his country which was in a time period where people of his color were not respected. He takes this and uses it as his reason to not go to war and support and country that took his father away from him. This shows that the actions that were taken towards him had negative consequences that show through his demeanor in the play and that the treatment towards him was wrong, allowing his actions to be justified.
