It helps readers understand how Alfonso truly feels about himself. Hope this helps. :)
I chose the 1971 film adaptation by Roman Polanski. I found that the text and film versions are extremely similar.The only distinction lies in the essence of the media that covers it.In the film, the portrayal of the scene is graphical and vibrant.In reality, you see Banquo falling to the floor, dead.In reality, you see Banquo falling to the floor, dead.
In terms of impact on the viewer, Roman Polanski's rendition of this scene is not only accurate but also strong.The specifics are all consistent with the text version: the characters and the environment are the same.The film version captures the character of Banquo to perfection: a courageous and better man than Macbeth, who at the moment thinks only of his son.To ensure Fleance gets to safety, he sacrifices himself.
I think Lady Macbeth wasn't involved at all because Macbeth does not tell her. Also, Macbeth does not want to keep her worried. So Macbeth says "Be innocent of the knowledge, dearest chuck, / Till thou applaud the deed.". This means that Macbeth is telling Lady Macbeth to digest the deed about Duncan first. This is what i remember its been a while since i read the book. But hope this helps.
