ANGIOLINA: He hath been guilty, but there may be mercy.

BENINTENDE: Not in this case with justice.

ANGIOLINA:Alas! signor,
He who is only just is cruel; who
Upon the earth would live were all judged justly?

George Gordon, Lord Byron (1788-1824) English poet

Marino Faliero, Doge of Venice, Act 5, sc. 1 (1821)
