Then I am sorry to say that there can have been no extenuating circumstances.

You entered his Highness's bedchamber, you did not even speak to him, you drew your sword and you killed him.

All this shows that you went there fully determined to commit the crime.

But with regard to its motive, this strange confession of your daughter's makes that quite clear.

She had been extremely imprudent with Don John, you were aware of the fact, and you revenged yourself in the most brutal way.
