He dismounted with a ruthful face.
"Raiding with Morgan"
Byron A. Dunn
And my heart was knit as it never had been before, to this young knight who had shed his blood in my behalf; but while I gazed down right lovingly into his face the Swabian came close up to him with ruthful eyes, and from those of the wounded man there shot at me a glance so full of hate and malice that I shuddered before it.
"The Complete Historical Romances of Georg Ebers"
Georg Ebers
Why, assure thee, Lucius, 'Twill vex thy soul to hear what I shall speak; For I must talk of murders, rapes, and massacres, Acts of black night, abominable deeds, Complots of mischief, treason, villainies, ruthful to hear, yet piteously perform'd; And this shall all be buried in my death, Unless thou swear to me my child shall live.
"Titus-Andronicus"
Shakespeare, William
