Here is a comparison of Macbeth's allegiances to good and evil before and after he commits the murder of King Duncan:
Before the Murder:
- Good: Macbeth is initially loyal to King Duncan and Scotland. He is a brave and honorable soldier, and he is well-respected by his peers.
- Evil: Macbeth has some dark thoughts and desires, but he is able to control them. He is not yet willing to commit evil acts to achieve his goals.
After the Murder:
- Good: Macbeth's allegiance to good begins to fade after he kills Duncan. He becomes increasingly guilt-ridden and paranoid, and he begins to lose sight of his moral compass.
- Evil: Macbeth's allegiance to evil grows stronger after the murder. He becomes more ruthless and ambitious, and he is willing to do anything to maintain his power.
Macbeth's journey from good to evil is a tragic one. He is a complex and conflicted character, and his downfall is a cautionary tale about the dangers of ambition and unchecked power.
