No one is born evil, they become that way, through circumstance and choice. In the book, Macbeth was well-respected and righteous. "The service and the loyalty I owe, In doing it, Pays itself.. Which do but what they should, by doing everything safe toward your love and honor." (1.4.22-24) The judgement of someone should not be based on reputation, but by the righteousness of that person. Often times, people put on a "mask" pretending to be someone they're not. However, when faced with challenges and competition their true colors come out. "I dare do all that may become a man; who dares do more is none." (1.7.45-46). Being highly thought of by others, while gaining power motivates a person to do many things whether they are right or wrong. Power changes people by taking over their lives, eventually destroying it.
The way a person overcomes challenges while trying to obtain power and success defines their character. “The castle of Macduff I will surprise, seize upon Fife, give to th’edge o’th’sword his wife, his babes, and all unfortunate souls.” (4.1.150-153) Macbeth believed many people were out to get him and ended up murdering them and their family so they could not accede his throne. He was cruel and heartless. He did everything in his power to keep a person from taking over his reign. “I have supped full with horrors; direness, familiar to my slaughterous thoughts”. (5.5.14-15) In the beginning of the book, Macbeth was a good, well-respected man in his town. Over time, he became ruthless and evil trying to gain more and more power.
With all the wrongdoings a person may commit, there comes a form of punishment. “Infected minds to their deaf pillows will discharge their secrets.’’ (5.1.64-65) Lady Macbeth committed an act of murder and wished to be feelingless. As time passed, she was overtaken by guilt and eventually killed herself. “Yet I will try the last. Before my body I throw my warlike shield.” (5.7.61-62) The punishment Lady Macbeth and Macbeth served for all their crimes were their unhappy disgruntledness. Macbeth gained power through all his crimes, but in return lost his happiness and his wife.
Power can cloud a person's judgement causing them to make unreasonable, hasty decisions. The need for power and success is so strong that a person will do anything, no matter the consequences, just to gain it. Happiness is corrupted in the pursuit of trying to gain power. Often times, happiness is cast aside so that power can be accrued.
