Explain how the play deals with masculinity and manhood?

Troy Maxson is a man who takes seriously his responsibility for his family. His seriousness also becomes his greatest liability. Troy is a man caught between his own desire for freedom, embodied in his affair with Alberta and his fathering of an illegitimate child, and his fierce sense of loyalty to his wife, children, and brother.

Troy's sense of responsibility comes from his own father's bitter care for him and his siblings. His father's loyalty to his family can be seen as poisonous; his father's betrayal poisons his own relationship with Corey. Ultimately, Troy becomes his father. He abandons Rose for another woman and stubbornly refuses to repent for his sins. He also abandons his own brother and son, severing his relationships in his own quest for freedom. Troy demonstrates the idea that responsibility becomes as much a liability as a virtue.
