Reddit r/confession Story
now, i remember there was an adult character (cant remember gender) who was telling someone about an event in their childhood, they told about how they drowned a baby(i think sibling) more or less on purpose because(i think) jealousy and when they held the babies head underwater they liked the feeling of power, and when the baby stopped moving, they were glad about it at first, until the finality of their actions became apparent, at which point they started regretting it and then it haunted them for the rest of their life
pretty sure it was a movie or tv show, pls help
