Lady Macbeth's mental disorders are evidences of her failure to suppress

conscience, which eventually, ends her tragic life by committing suicide.

Any grammatical error?? Thanks!!

She says "But who would have thought the old man would have so much blood in him…/Banquo is buried/ He cannot come out of his grave" (5.1 25-40).
