In my opinion macbeth is the one to blame in the murder because he is the actual killer you can't make someone kill someone you can only instigate it. On page 329 line 62 “ i have done the deed’’ in my opinion the killer should be the one accused and punished. Macbeth let lady macbeth get to him just by calling him a coward and that is his fault. Line 44-46 “ Who said that? Why, my worthy lord, you let yourself become weak when you think about things in this cowardly way” and that phrase
