The defence speech for Macbeth as a murderer

Ladies and gentleman of the jury. Sitting before you today is a man accused of the murder of Duncan, the King of Scotland. The prosecution will portray Macbeth as an ambitious man, one who plotted to murder his own cousin, so that he could lay claim to the title of the crown. But the issue in this case is not whether Macbeth murdered the deceased. This fact is not disputed. What you must determine is …

…mind, it is on the prosecution to prove, beyond reasonable doubt, that Macbeth was not a changed man after the meeting with the witches. That they did not possess his mind and brainwash him. They must also prove that Lady Macbeth did not blackmail and dishonour him, forcing him to continue with the crime that she had planned. If they fail to meet this onus, Macbeth is entitled to be acquitted of murder. Thank you.
