That’s a great point Gerda. A sin is something we feel guilty, or personally responsible for. Mistakes we do them all the time but don’t feel guilt or responsibility for. We correct them or simply forget them! Sin, the word seems to have originated in a religious context but it doesn’t have to be seen as religious.
As long as a person does something wrong, defined by the action in its context, and feel guilt about it, then people would use the word sin.
In the Western world secular humanists retain Christian morality but without the attendant belief in the Christian God. So we still use the word sin but in a more secular way!
