Was Lady Macbeth to blame for Macbeth's downfall?

In
Shakespeare's , Ladyis partly to blame for Macbeth's downfall. 

• They both react to the predictions that Macbeth will be king in the same
  way, even though separated:  they both instantly jump to the conclusion that killingis what will
  be necessary for the prediction to be fulfilled. 
• When they do meet,
  they suggest in their conversation that they should assassinate Duncan that night while he is
  sleeping in their castle.  Macbeth is still deciding, butis already certain.


• Macbeth decides not to kill Duncan, but Lady Macbeth talks him into it by using
  manipulation and questioning his manhood.
• But when Lady Macbeth has an
  opportunity to kill Duncan herself, she cannot go through with it.
• Macbeth
  can, and does, kill Duncan himself.
• Lady Macbeth just does a lot of talking
  and planning, but Macbeth does the killing.  Furthermore, Lady Macbeth has nothing to do with
  the rest of the killings that occur--those are all Macbeth.  She is shocked when he kills the
  grooms, and is unaware when he orders the killings ofand 's family.

Ironically, if Lady Macbeth would have had more to do with the later
killings, Macbeth might have gotten away with them.  It is only when Macbeth varies from his
wife's plans or acts without her knowledge that he makes mistakes and creates
suspicion.
