I am a logic-based person, so things like “curses” aren’t a real thing- except in this world it seems like some people really are cursed. I, for one.
I mean, logically, it’s bc ppl who are down-trodden get even more stepped on and ignored and screwed in life. The more bad that’s happened to you, the more bad that gets piled on, and the less “normal” ppl want to help you out or want anything to do with you (be friends, etc).
