Macbeth contemplates the murdering King Duncan and doesn't think it's the right thing to do. Lady Macbeth mocks him of his cowardliness about not wanting to murder King Duncan and convinces Macbeth to murder King Duncan and makes him a plan.
Why would I want to kill King Duncan? I honestly don't want too.
Hello my wonderful wife. How are you doing today?
Actually I'm feeling quit disappointed right now.
Why are you being such a wuss? The murder is all set up for you all you have to do is murder King Duncan!
Why can't he just murder the guy? It's not like it's that big of deal. Ughhhhh
Okay fine I will. What's the plan?
This evening we will drug the guards and kill Duncan and blame it on the guards!
