Fyodor Dostoevsky

“ Think- you must visit him; though he is ruined, he is innocent," broke like a challenge from Alyosha. "His hands are clean, there is no blood on them! For the sake of his infinite sufferings in the future visit him now. Go, greet him on his way into the darkness- stand at his door, that is all.... You ought to do it, you ought to!" Alyosha concluded, laying immense stress on the word "ought."
"I ought to... but I cannot..." Katya moaned. "He will look at me.... I can't."
"Your eyes ought to meet. How will you live all your life, if you don't make up your mind to do it now?" ”

“ Katya concluded irritably. "Can such a man suffer? Men like him never suffer!" There was a note of hatred and contemptuous repulsion in her words. And yet it was she who had betrayed him. "Perhaps because she feels how she's wronged him she hates him at moments," Alyosha thought to himself. He hoped that it was only "at moments." In Katya's last words he detected a challenging note, but he did not take it up.
"I sent for you this morning to make you promise to persuade him yourself. Or do you, too, consider that to escape would be dishonourable, cowardly, or something... ”

“ Katerina Ivanovna was pale and terribly fatigued, yet at the same time in a state of hysterical excitement. She had a presentiment of the reason why Alyosha had come to her.
"Don't worry about his decision," she said, with confident emphasis to Alyosha. "One way or another he is bound to come to it. He must escape. That unhappy man, that hero of honour and principle- not he, not Dmitri Fyodorovitch, but the man lying the other side of that door, who has sacrificed himself for his brother," Katya added, with flashing eyes- "told me the whole plan of escape long ago. ”
