“What’s going on, my lord? Why are you keeping to yourself, with only your sad thoughts to keep you company? Those thoughts should have died when you killed the men you’re thinking about. If you can’t fix it, you shouldn’t give it a second thought. What’s done is done.”
The Shakespearean play, “Macbeth”, is about a Scottish general who’s given a prophecy by three witches that he would soon become King of Scotland. In the story, Macbeth is persuaded by his ambitious wife to commit regicide in order to fulfill the prophecy. He is morally skeptical of this but does it anyway during the King’s visit to Macbeth’s castle. He murders the King in his sleep, and after the corpse is discovered, also murders the guards who were there during the scene but had been drugged by Lady Macbeth. Funnily enough, there was never any proof that Lady Macbeth (in terms of historical accounts) had anything to do with helping Macbeth murder King Duncan. It’s all a lie and was created as a fictitious plot for the play, but must not be taken as historical fact. Was she correct in her statement, though? Certainly, once something is done, there is no going back. Do not trouble yourself over things you have no control of, rather live the present, look towards the future and exclude the past. The only use one may have of events from the past is not that of grievance, but of reflection to help you do better in similar circumstances at any given time in the future.
