darry caring for pony isn't solely something that's from the heart or because he simply is a "good" older brother — he is caring for ponyboy out of obligation, obligation that is tied up in his sense of masculinity and adulthood. to say that he's raising ponyboy purely from the depths of goodness in his soul ignores that darry's "parenting" of ponyboy has been violent, has had all the hallmarks of silent gen's viewpoints on masculinity and honor, and that if he failed to parent ponyboy, he would in essence be failing to be a "real" man. if he fails to care for ponyboy, his masculinity, his reputation, and pride is in jeopardy. that's a fact of the matter, and it is a huge piece of why their relationship is entirely so dysfunctional because if there was a societal acceptable way for him to give pony up that didn't also sacrifice his ties to masculinity, worth, and pride, i believe he would do it. pony is an extension of his manhood, of his ideas of how men govern themselves, of how darry is perceived. and he simply can't let him go so he's forced to do what's right even if "doing what's right" is actively fracturing their relationship.
