Lady Macbeth was an accessory and an accomplice to her husband in the murder of King Duncan I [d. August 14, 1040]. It was in fact she who came up with the plan to help Macbeth [d. August 15, 1057] carry out the killing of his sovereign and the two royal guards without any blunders. She planned to get the guards to drink too much of drugged drinks. They then would be incapable of defending their ruler. Neither would they be capable of defending themselves when Macbeth turned the daggers on them as well.

When Macbeth doesn't kill Duncan, lady Macbeth decides to insult and question his manhood. Her beliefs are that manhood can only be defined through murder.

In "Macbeth," after he had slain Duncan, Macbeth went on to commit additional murders to cover his tracks, even without his wife's prompting. Before the death of Duncan, he needed the pushing of Lady Macbeth to kill. Once the deed was done, however, he came across as someone willing to do whatever it took to keep his new status and not be exposed.
Lady Macbeth made the plan. The grooms who were to be guarding the king were to be made so drunk that they would not wake.

Decisions are always hard to make, but have to be made everyday. People tend to put pressure on others to force them to make the wrong decisions. In Macbeth's case, Lady Macbeth is highly responsible for the evil doings of Macbeth, by forcing him to make the wrong choices, which puts his leadership at stake. She urges her husband to kill Duncan and become king, but is eventually driven to madness and suicide by her guilt over the bloodshed that follows. If it weren't for Lady Macbeth, Macbeth never would have killed anyone. At first, Macbeth felt he had no reason to kill King Duncan, because of the witches' prophecies which stated that in the future, he will become king. "If chance will have me king, why, chance may crown me without my stir." However, when Lady Macbeth found out about the prophecy that stated that Macbeth will become king, she immediately felt reason to murder him. "Is too full o' the milk of human kindness" shows that Lady Macbeth considers Macbeth to be a "wimp," and that she'll have to do this all by herself. "Leave all the rest to me" clearly states that Lady Macbeth takes control over Macbeth's thought which was not to kill Duncan, for he found no reason to. Lady Macbeth continues to convince and persuade Macbeth into her "plan" which is to kill King Duncan. Macbeth agrees to follow Lady Macbeth's thoughts and kills King Duncan. He regrets his actions afterward, which is proof that he never was willing to kill him in the first place. Macbeth has become deeply involved with murder, and eventually kills several others. This is proof that Lady Macbeth has transformed Macbeth into being a greedy, coldhearted human being, by saying things such as "Are you a man?" She undermines his masculinity, to make him feel at fault, and have it her way. Eventually, Lady Macbeth is driven to Madness by the guilt she holds on her shoulders, and ends up committing suicide. If it weren't for Lady Macbeth, Macbeth would have never killed anyone.
