Original sin is a cancerous dogma that cucks its adherents to the Church/State—like a religious version of white-guilt. Islam teaches the doctrine of original sin as well, in case you weren't aware; it's much easier to justify evil when the concept is touted as intrinsic. Ask yourself why the Church would want you to believe that your innocent child is born a sinner. You should explore the philosophical implications as well as the practical applications of what you preach.
