The theme of "The Outsiders" is friends are family and family never abandon each other.
"Was Dally a good friend of yours?"
"I killed him"
"Was he a real goodbuddy of ours? Darry said, 'Yes, sir,' looking straight at the judge, not flinching; (Pg. 168)"
"Darry hit me."
"'I killed him,' he said slowly. 'I killed that boy.' Bob, the handsome Soc, was lying there in the moon-light, doubled up and still. (Pg. 56)"
"Johnny died. You read about people looking peacefully asleep when they're dead, but they don't. Johnny just looked dead. Like a candle with the flame gone. I tried to say something, but I couldn't make a sound. Dally swallowed and reached over to push Johnny's hair back. "Never could keep that hair back... that's what you get for tryin' to help people, you little punk, that's what you get... (Pg.148-149)"
"That is what you get."
"'Johnny?' I called, and started when he rolled over and jumped up almost under my feet 'Come on, Johnny, we're running away.' Johnny asked no questions. We ran for several blocks until we were out of breath. Then we walked. I was crying by then. I finally just sat down on the curb and cried, burying my face in my arms. Johnny sat down beside me, one hand on my shoulder. 'I don't very often. It was Darry. He hit me. I don't know what happened, but I couldn't take him hollering at me and hitting me too. I don't know... sometimes we get along okay, then all of a sudden he blows up on me or else is naggin' at me all the time.' (Pg. 50-51)"
