flagitiousness

His offence was not flagitiousness but the vulgarity, ostentation, and political inexperience of a parvenu.

Contrasting the humanity of the present age with the barbarism of antiquity, great stress has been laid on the savage custom of exposing the children whom their parents could not maintain; whilst the man of sensibility, who thus, perhaps, complains, by his promiscuous amours produces a most destructive barrenness and contagious flagitiousness of manners.
