The best payback would have been a progressive combination to maximise the suffering
Castration here as that was standard
This crap about bleeding out in wrong, slaves were regularly castrated, same method used on steers, and the hot end of the knife would cauterise the wound
There is a method to castrate that doesn't even need cauterisation, you can look up a clip of that if you're curious
First stage, castrate him
Second stage a public naked whipping
Have him watch his wife get gang raped first by the white farm hands, then the slaves
Then give him to the Mandingo for sparring practice, the added advantage that your prize Mandingo, the one we saw earlier, gets better for the practice and wins you more fights
Finally give what's left of him to the mines for the ending as described
