Why does Johnny think Dally is a hero?

In Chapter 5, Johnny and Ponyboy are hiding out in the abandoned church on Jay Mountain and begin to read the novel Gone With the Wind. Johnny finds the story fascinating and is especially interested in how the Southern gentlemen were portrayed. Johnny then tells Ponyboy that he thinks Dally is gallant. Initially, Ponyboy finds Johnny's comment perplexing because Dally lacks manners like the Southern gentlemen in the novel. However, Johnny explains to Ponyboy how he witnessed Dally selflessly take the blame for a crime that Two-Bit committed. Johnny says that when the police arrested Dally, he gallantly remained calm and did not deny anything. In addition to witnessing Dally act courageously during difficult situations, Johnny has a close relationship with him. Dally views Johnny as a younger brother and truly cares about him. When Johnny is trapped inside the burning church, Dally enters the building and rescues him. Johnny not only views Dally as a hero for acting brave under pressure but also because he saved his life.
