This Wuthering Heights bad boy's story is told in bits of puzzling and disturbing pieces. He is known for his quick temper and vengeful nature, and arguably, his only redeeming quality is his love for Catherine. Apart from that (and also because of it), he is quite unpleasant, but we love him regardless.
Best bad-boy line: "I have no pity! I have no pity! The more the worms writhe, the more I yearn to crush out their entrails! It is a moral teething; and I grind with greater energy in proportion to the increase of pain."
