place help!!!will macbeth and his wife be happy as king and queen?why(not)

It does not take long to figure out that this couple is pretty dysfunctional. Both are greedy but, initially Lady Macbeth is aggressive. Macbeth is scared of his wife. The dynamics change as the play unfolds but their dysfunctionality does not. Both are inept murderers while remaining emotionally isolated from each other through the whole play.
