" Tyranny is a habit which may be developed until at last it becomes a disease. I declare that the noblest nature can become so hardened and bestial that nothing distinguishes it from that of a wild animal. Blood and power intoxicate; they help to develop callousness and debauchery. The mind then becomes capable of the most abnormal cruelty, which it regards pleasure; the man and the citizen are swallowed up in the tyrant; and the return to human dignity, repentance, moral resurrection, becomes almost impossible. "

― Fyodor Dostoevsky , The House of the Dead
