How does Macbeth Act just before he murders Duncan

Macbeth is talking to himself again. He hems and haws over the consequences hell face if he decides to commit murder. He knows that killing Duncan could mean bad news for him and just about everyone else in Scotland. When Lady Macbeth enters, he tells her he cant go through with this sordid plan. But shes got other ideas. Trying to psych her husband up for some regicide, she tells him hes not much of a man if he cant find the courage to kill the king. Then she hatches a plan: theyll wait until Duncans asleep, get his servants drunk, kill the king in his bed, and blame it on the servants. Sounds good to Macbethhe commits to the plan.
