ISABELLA. [_Kneeling_.] Most bounteous sir, Look, if it please you, on this man condemned As if my brother lived. I partly think A due sincerity governed his deeds Till he did look on me. Since it is so, Let him not die. My brother had but justice, In that he did the thing for which he died. For Angelo, His act did not o’ertake his bad intent, And must be buried but as an intent That perished by the way. Thoughts are no subjects; Intents but merely thoughts.
