How do Ponyboy's feelings toward Randy reflect the conflict between the Socs and the Greasers?

At first, Ponyboy sees Randy as a violent Soc to be avoided; he is Marcia's boyfriend, and is involved in jumping the Greasers. But in Chapter 7, they have a conversation in Randy's car, and Randy explains why he is leaving town instead of attending the rumble. He says, "You can't win, even if you whip us. You'll still be where you were before - at the bottom. And we'll still be the lucky ones with all the breaks. So it doesn't do any good, the fighting and the killing. It doesn't prove a thing. We'll forget it if you win, or if you don't. Greasers will still be greasers and Socs will still be Socs." Ponyboy begins to see Randy as someone who can appreciate sunsets, and feels a connection to him regardless of their different social statuses.

However, in Chapter 11 when Randy comes to visit Ponyboy at home, Ponyboy's denial about Johnny's death and the events leading up to it cause a rift between the two boys again. Ponyboy decides, "He was just like all the rest of the Socs. Cold-blooded and mean."
