Who was Macbeth's motivater to kill

I believe that Lady Macbeth was Macbeth's motivate to kill. I believe this because she was the dominate person in the couple and always wanted him to be a bigger man, Glamis thou art, and Cawdor; and shalt be What thou art promised. Yet do I fear thy nature; It is too full o' th' milk of human kindness.(Shakespear, act IV). As you can I see Lady Macbeth was always pushing on Macbeth to the point to where it unleashed a murdering beast. PLEASE SEE MY EMAIL!!!!!!!!!!!!!!!!!!!!

I chose white house down for my movie comparison because in both stories 1 person is trying to kill and take over as a supreme leader. In White House down, A secret service agent tries to take over the white house and murder the President to take over the U.S. In Macbeth, Macbeth kills his king to take over the throne but eventually it all falls apart. In the end both cold blooded killers end up failing to achieve their goal.https://www.youtube.com/watch?v=ndpNqYoN2DM
