For both questions, the answers are NO. He didn't want to face up his mistakes and take control over the whole situation, instead he decided to play coward and hide somewhere to hide away from the problem at hand. He does not live up to his responsibilities and choose the easier way out- to hide away from everything and put his head underground just like a ostrich and run away from any obstacles and setbacks in his life. He choose to escape from realism as he feared that people might punished or even scold him. He wanted to escape into another world, where people will respect his own character.

He thought that having a gun will put a mark on his life and he will progressed into manhood and become real man and people will respect him for who he was. He pictured the gun as a symbol for power and honor but his fallacy proved to be his downfall as people criticized him and make laughing jokes out of his miserable state. And also, he would be in real hot soup with the law enforcement agencies as owning a gun is tantamount to a real crime as carrying weapons is against the law, so leaving right now would be a huge mental blow to his family, as they had to cleared up the terrible mess he left behind due to his selfish decisions and make amendments to his wrong deed, it would be very tiring and painfully tired for the whole family to get burden up just because of his selfish character. He had make a lot of bad and worse decisions in his life as he could not accept the reality check and decide to flee from the truth. He didn't become a true man and this shows how immature and selfish he is to anybody, even to his family members. That also shows that he didn't "coming-of-age" in the end of the story and hadn't reached maturity yet. This ending surely portrays accurately the title of the story "The Man Who Was Almost a Man".
