“Terror made me cruel . . .”

“Terror made me cruel; and finding it useless to attempt shaking the creature off, I pulled its wrist on to the broken pane, and rubbed it to and fro till the blood ran down and soaked the bedclothes...”

“How cruel, your veins are full of ice-water and mine are boiling.”

“He... was attached by ties stronger than reason could break -- chains, forged by habit, which it would be cruel to attempt to loosen.”

“You teach me now how cruel you've been - cruel and false. Why did you despise me? Why did you betray your own heart, Cathy? I have not one word of comfort. You deserve this. You have killed yourself. Yes, you may kiss me, and cry; and wring out my kisses and tears: they'll blight you - they'll damn you. You loved me - what right had you to leave me? What right - answer me - for the poor fancy you felt for Linton? Because misery, and degradation, and death, and nothing that God or Satan could inflict would have parted us, you, of your own will did it. I have no broken your heart - you have broken it; and in breaking it, you have broken mine. So much the worse for me that I am strong. Do I want to live? What kind of living will it be when you - Oh, God! would you like to lie with your soul in the grave?”

“Mr. Heathcliff, you're a cruel man, but you're not a fiend; and you won't, from mere malice, destroy, irrevocably, all my happiness.”

“It would degrade me to marry Heathcliff now; so he shall never know how I love him: and that, not because he's handsome, Nelly, but because he's more myself than I am. Whatever our souls are made of, his and mine are the same; and Linton's is as different as a moonbeam from lightning, or frost from fire.”
