Can you explain what makes something morally wrong?

When I was a child, my father told me that he was just waiting for me to turn 18, because then it would no longer be his responsibility. I ignored him at the time because I was only 9. However, when I was 15, my parents told me that they could legally abandon me if they wanted to, but they chose not to. He showed me the paperwork to prove it to me, and I can't get this image out of my mind. My father is a happy, well-adjusted person who loves me more than anything, but he showed me this paperwork to make it clear that he didn't have to raise me or take care of me. He told me that he chose to care for me, and I guess he wanted me to be grateful for his generosity.<br><br>I can't stop thinking about this. Even though my parents love me, this situation makes me question what makes something right or wrong. If my father had abandoned me at 15, it would be wrong, but I don't know how to explain why it would be wrong. If my father chooses to care for me, it is right, but he doesn't have to do it.<br><br>I feel confused and I don't know what to think.<br><br>Please help me make sense of this.<br><br>I posted this because I believe that philosophy is about making sense of the world, and I want to hear your thoughts.<br><br>Thank you very much for your time.<br><br>Edit: Thank you so much for all your responses! I really appreciate all the effort you put into them, and for the most part, I agree with your thoughts. It doesn't make sense to me that my father is not responsible for raising me, and I think you are right when you say that it is the right and morally correct thing for him to do. Thank you for all your comments. I have learned a lot.
