Well, when you get 'em straightened out on slavery, we still have bitter herb abortions, dashing childrens against stones, menstruating women expelled from church, encouraging the devout (and gullible) to swill poison and aggravate cobras, rescinding Jesus ban on remarriage following divorce, and probably quite a bit more . . . .
The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.
