I need someone to write me a research paper on macbeth

I need a typed research paper about Macbeth being a tragic hero. 5 – 6 pages worth with a cite page At the end and in MLA format. My thesis is Macbeth is not really to blame for the tragic events of the play. Also I need it to talk about the events in the story about the killing of Duncan and if the witches had anything to do with It. Could I get some help.
