Humans enjoy free will. Every person inherently has a potential for good and a potential for evil. Humans also have innate qualities and weaknesses imbued into them from birth, although an individual has the will to decide which qualities and weaknesses they wish to improve further. If our strengths outweigh our weaknesses, we tend to be better individuals, but if our weaknesses outweigh our strengths, we tend to be the opposite. Our greatest weakness is that we are purely selfish and prideful. Our judgments tend to be distorted by the pleasures and pains of the moment. In William Shakespeare's Macbeth, the tragic hero, Macbeth, begins as a prestigious and honorable soldier but he succumbs to the dark shroud of ambition that falls over him. Although Lady Macbeth and the three witches pester him to pursue his desires, Macbeth chooses to follow them, despite being fully aware of the inhumanity. He in turn assassinates King Duncan to secure his crown. This marks the beginning of a dark and cloudy path that leads to more bloodshed of innocent lives under the command of none other than the doomed tyrant Macbeth. The brutal massacre of the Macduff family brings Macbeth and Macduff into the final duel and Macbeth eventually meets his eternal sleep. The darkness and weakness of human nature is best illustrated by Macbeth and Lady Macbeth, who crave power and ignore their intrusive impulse towards human decency and convince themselves that they can live with such heinous acts because of their ego and their desires. Macbeth shows how far he would go to achieve his ambitions and he strays from the righteous path. He begins to walk the path of darkness under the leadership of the three witches and Lady Macbeth. At the beginning, Macb... in the middle of a sheet of paper... is the central point of the play, she is considered the embodiment of evil. Most of what is vile in human nature is demonstrated in the play, but the deepest darkness in human nature is ego and desires. Shakespeare has a deep understanding of the ugly side of human nature and he exploits it in many of his writings. “Macbeth” does a remarkable job of depicting human weaknesses and the evil that comes from them. Ego and desire cloud our judgment and morality. We tend to ignore our innate human qualities when it comes to dealing with these two excruciating aspects of human nature. The ego only has absurd desires. The ego is not the person, it is only the image you have of yourself, the idea you have of who you are. The ego and desires are relatively related to each other, and they are one but two totally different ideals. These are the greatest evils and weaknesses of humans.
