Why is the rumble ironic in The Outsiders?

The rumble in "The Outsiders" is ironic because it ultimately fails to resolve the deep-seated conflicts between the Greasers and the Socs. Although the characters believe that winning the fight will prove their superiority and validate their identities, the violence only leads to more pain and loss, particularly with the death of Johnny. Additionally, the rumble highlights the futility of their rivalry, as the characters realize that the social divisions they fight over are meaningless in the face of real tragedy. Ultimately, the rumble underscores the futility of their struggles, making their actions seem senseless.
