Macbeth - Is Malcolm's assessment of Macbeth and Lady Macbeth justified?

In the play, 'Macbeth' by William Shakespeare, Malcolm refers to Macbeth as a "Butcher" and, Lady Macbeth as a "fiend-like queen". This is only true to an extent as although this assessment of their character would have made it easier to cope with the consequences of their actions their feelings finally overcame them. When Malcolm calls Macbeth a "butcher" then he is implying that Macbeth kills people without feeling and emotion as if it was …

…sign of being a butcher, he kills Macduff's family purely out of spite but he shows sign of remorse and guilt that prove he isn't a "butcher". He shows signs of bravery right up until the end of the play. Lady Macbeth shows the same signs of remorse and guilt as Macbeth, she can't be a fiend, as a fiend would kill out of evil and not out of love for her husband. Steven Hendrie
