Even the most harmless manifestations of natural affection between male and female he considered disgusting, indeed indecent, and if these were carried any further he held it to be among the greatest of crimes.

He was one of those who, if he had the power, would have hounded any poor girl who, in the country phrase, "had got into trouble," to the river brink and over it, as a creature not fit to live; or if she escaped destruction, would have, and indeed often had, pursued her with unceasing malignity, thinking that thereby he did God service.
