"I'm a sinner who took my mother's life, so no one could ever love me"? What the hell are you talking about, you fool!!

At a party being held at my place, I saw a child being treated coldly by their family. Apparently, their mother died when the child was born. Ever since, the father and older siblings have treated them as if they were their enemy. I'd never seen it before, but the family's behavior was notorious enough to be the subject of gossip. I hate this kind of thing, you know? A little while back, my best friend suddenly entered seminary school. And it was for this exact reason. So, acting like an immature adult, I got angry and yelled, and threw myself between this pathetic old man and the child who was cowering under his abuse. In front of me, you're the one doing something shitty like that. The kid being verbally abused isn't my best friend, and this old man isn't his father either—I know that. But I can't forgive it. It's an eyesore and an earache. So—take my displaced anger, why don't you? It's the same thing you're doing to that child. "Every time you treat that child as your enemy, every time you mistreat them, every time you scold them unfairly, it's like you're saying, 'Oh thank you so much for taking revenge on my behalf! I gave birth to this child, but that doesn't matter! Because this child took my life! Please mistreat them more, make them suffer more, corner them, and make them understand!' You're acting like that kind of nasty woman who enjoys hurting her own child, and even after you die, your family and husband spread that reputation—man, that's just pathetic." Even after death, for the family to say, 'she blamed the newborn child for her death and wanted revenge taken on them'—honestly, the wife has no peace even in death. 'I'm a sinner who took my mother's life, so nobody will love me'? That's complete bullshit!! The setting is vague. This is a side story about the best friend of the protagonist from "Why Do You Also Live?"—you don't need to have read that one. Posted on Alphapolice and Kakuyomu.
