Secrecy becomes a well-developed characteristic in several characters after the death of Duncan. Clearly, the consciences of the responsible characters begin to disturb them. As the play progresses, Macbeth's conscience bothers him so much that he can neither sleep nor eat, he has nightmares and frightening visions, and begins to lose control of his actions. Even though Macbeth is an evil character, his conscience worries him deeply for the crimes he commits. "One cried "God bless us!", and "Amen" the other,/ Listening their fear, I could not say "Amen",/ When they did say God Bless us!" But wherefore could not I pronounce "Amen"?/ I had most need of blessing, and "Amen" Stuck in my throat" (2.2.27-33). Macbeth's conscience feels so guilty, after the first murder, that he cannot reply Amen at the end of a prayer. As the play further matures, Macbeth becomes very overprotective of his secrets and develops a lack of communication about them with his wife. Macbeth becomes so frightened that someone may discover his secrets that he decides to trust no one but himself. He silences his wife's questions: "Be innocent of the knowledge, dearest chuck,/ Till thou applaud the deed" (3.2.45-46); indicates that Macbeth no longer even trusts his wife with his secret mischievous plans. As a result, Macbeth becomes so paranoid that he puts spies in every corner of the country, to know exactly what people are saying about him. By isolating everyone from himself, in order not to reveal his secrets, Macbeth terminates with no one to rely one. He becomes a trapped victim of his own actions. .
I have lived long enough: my way of life.
Is fallen into the sear, the yellow leaf,.
And that which should accompany old age,.
As honor, love, obedience, troops, and friends,.
I, must not look to have; but in their stead,.
Curses, not loud, but deep, mouth-honour, and dare not.
(5.3.76) .
As a result, Macbeth has no one to share his thoughts with, no son to pas on his crown to, and no honor in himself.
