Words can push people to do things they know is wrong, feel loved and thankful, and even be encouraged to do things they cannot imagine themselves being capable of. Words carry the power to build or destroy someone and, therefore, should be used wisely and with caution. This shows that Macbeth was easily affected by the words of his wife when she insulted his masculinity. From all these points, it is clear to the reader that Macbeth was a moral and loyal soldier who was brave and kind, but easily affected by his wife's words that labeled him as not masculine enough.
Secondly, Macbeth turns ambitious and treacherous as the story progresses. In the beginning of the play, a scene foreshadows Macbeth's internal conflict with himself in the future. After winning the war, the first words that Macbeth utters to Banquo are, "So foul and fair a day I have not seen" (I.iii.38). In modern language, Macbeth is saying that the day is beautiful and unpleasant at the same time. What he implies from this is that the day is good because they won the battle, but bad because they had many casualties. In a deeper sense, this line of Macbeth's mirrors the words of the witches at an earlier time, which is as follows, "Fair is foul, and foul is fair" (I.i.10). This could foreshadow Macbeth's future connection to the witches, the dark forces, and eventually, his place in fate. Also, this line foreshadows Macbeth's future feelings and self-conflict when he is thinking about killing the King, because of the contradictory nature of these words, since a day cannot be good and bad at the same time. These words are also an example of equivocation because the saying is contradictory and is a play on words. Connecting this to modern day life, many people are faced with difficult decisions in their life that tears them apart, because of the self-conflict that comes from trying to make such choices.
