Then seek forgiveness. We worship our own self-will at the expense of another. Mankind went off the gold standard of idolatry sometime back in Exodus. That is what sin is. And to make things right, we see the enormity of the sin and we must seek forgiveness.
Sin has many levels.
There are sins that involve society. We know that. I suppose I could forgive my German relatives who may have been participants in all of that. I can forgive them Auschwitz and Dachau. But when the sin is directed to us, when we are directly and deliberately injured by sin, then it's not so easy.
