The Catholic dogma of original sin is correct, we are indeed broken, still good but damaged and with tendencies to evil. But about perfectability: we can't be perfect in this world. Yet Jesus told us: "Be perfect as your father in heaven is perfect." How can this be? We can't make this world perfect, the world to come is perfect. We can be perfect because we can live with God, and He will perfect us.
Day of Atonement: they say 'sorry' to God mainly, next to each other.
