Cruelty begins with the conviction that nothing is watching. Once a people persuade themselves that no eye records what they do, that the good has abandoned the world and judgment sleeps, every restraint dissolves. Blood fills the land and perversity fills the city precisely because the sense of being seen has died. The lie underneath the violence is that reality does not keep accounts.
But a person is always the witness to his own conduct, and something in him registers each betrayal whether he admits it or not. No man escapes that inner witness. To act as though you are unobserved is to corrupt the one observer you can never leave behind. The city becomes what its citizens believe about being seen. Tell yourself no one is looking, and you free yourself to become monstrous.
