Fair is a foul and foul is a fair

Fair is a foul and foul is a fair

"Fair is a foul and foul is a fair" it is said by the three witches at the end of the play's opening scene. When Macbeth heard the prophecy of the witches, he believes immediately on the prophecy of the witches. He is hungry for the power especially his wife who is Lady Macbeth. The prophecy can be either untrue or unbelievable but it can actually express the truth. He made a way on how to conquer the power and to be the king of the Scotland. He became selfish just to get the position. He killed people that can make his plan fails.

In reality, ambitious can lead to success but there's a foul behind it. We do like success and we can do everything to become successful. We can do evil things to others just to achieve what we want and we prove to ourselves that we are selfish. Do you ever think that winning in a certain war is an example of success? How about the people who struggle their life and died in a war? Good is bad. It seems fair but it is foul.
Witches are evil creature. They like fouls and hate fair so they are waiting to do evil things like their prophecies that can poison the mind of Macbeth. Life is unpredictable and people may change. We thought that we did something good but it could turn to be bad just for the sake of success and became ambitious to the power.
