Stupidity.................
The lines that show that Macbeth is on the verge of giving in to temptation, knowing very well that he is considering committing a terrible crime are:
<em> "Macbeth wonders to himself whether all the prophecies will come true"</em>. He knows that in order to become King, he has to commit a terrible crime, killing his cousin Duncan and he is thinking of doing this.
King shows that the struggle for freedom and equality is not over by giving examples of violent events that recently took place. This shows the discrepancy between the laws and what's really going on. Therefore, a further struggle is necessary if people want to succeed.
