SCENE V. Gloucester's castle.

Enter CORNWALL and EDMUND

CORNWALL
I will have my revenge ere I depart his house.

EDMUND
How, my lord, I may be censured, that nature thus
gives way to loyalty, something fears me to think
of.

CORNWALL
I now perceive, it was not altogether your
brother's evil disposition made him seek his death;
but a provoking merit, set a-work by a reprovable
badness in himself.

EDMUND
How malicious is my fortune, that I must repent to
be just! This is the letter he spoke of, which
approves him an intelligent party to the advantages
of France: O heavens! that this treason were not,
or not I the detector!

CORNWALL
Go with me to the duchess.
