From Wuthering Heights by Emily Bronte

'One might suppose you had never opened a Bible in your life. If God afflict your enemies, surely that ought to suffice you. It if both mean and presumptuous to add your torture to his!'

'In general, I'll allow that it would be, Ellen,' she continued. 'But what misery laid on Heathcliff could content me, unless I have a hand in it? I'd rather he suffered less, if I might cause his sufferings, and he might know that I was the cause. Oh, I owe him so much. On only one condition can I hope to forgive him. It is, if I may take an eye for an eye, a tooth for a tooth, for every wrench of agony, return a wrench, reduce him to my level. As he was the first to injure, make him the first to implore pardon; and then - why tehn, Ellen, I might show you some generosity. But it is utterly impossible I can ever be revenged, and therefore I cannot forgive him.'
