Macbeth is the most understandable of all the Sharkespares I have read. However, reading this book is like watching a horror movie and tempted to turn off the television but can not do it, because you want to see what happens next. I believe the witches have all the influence in the book. They trigger the bad and confussing aspects of the book. The book speaks of man's attempt to aquire power by the most unfair ways,which do not work out in the end. It brings death, diseases, lies ect. It speaks of unfair competition for gain and the negative consequence of it : - you can lose your friends. Overall, Macbeth is a good book because it has ,in it a message of the importance of fairness, trusting in God and not familiar spirits as well as teachings of the results of chaos.
