During his 1842 tour of the US, Charles Dickens met a southerner who tried to convince him that harsh treatment of slaves was against the self-interest of Southern slaveholders. Dickens’s response was devastating: “I told him quietly that it was not a man’s interest to get drunk, or to steal, or to game, or to indulge in any other vice; but he did indulge in it for all that. That cruelty and abuse of irresponsible power were two of the bad passions of human nature, with the gratification of which considerations of interest or of ruin had nothing whatever to do.”
