In "The Bride Comes to Yellow Sky" by Stephen Crane, you see the changing of Scratchy Wilson. When he first comes into the story he is depicted as someone who is the village drunk, he is calm most of the time, but every once in a while he gets drunk, and goes looking for a fight, mainly with Jack Potter. At the end of the story he is then greeted by Jack and his new bride and seeing this Scratchy calls off his fights. This goes to show that fulfilling your own life can affect more people then you know, and you have to act accordingly.
At the start Scratchy's fights disrupt the town, and he has a regular bought with Jack. He sees this as alright, and does not seem to be effected by what he does. But at the end when he is trying to pick a fight, he learns that Jack just got married, and he then comes to the realization that he is now going to be ruining his life with her, and calls off their rivalry. As a married man Jack is no longer the town sheriff, he is now a husband, he was no less of a person before this, but it took the marriage to make Scratchy realize it.
At the beginning of the story we also see that Jack also has a conflict. He thinks that by bringing his new bride home he is going to ruin his life in the town for a short while. He almost feels ashamed for not getting prior approval of the townsfolk before running off and marrying. But at the end it is actually his wife that gets him approval. By brining her along, Scratchy "approves" of him, and therefore does not carry out with his intention of a gun fight. So Jack's fear of acceptance was unfounded at the beginning, but plays a role at the end.
