Macbeth With A Plot Twist

This story would have a totally different meaning and plot if Macbeth earned the throne through doing something good. It would change the tone from evil and to heroic because Macbeth formed this great talent that would have earned him power of the throne. The plot would be different in that there would still be witches but the witches would inspire Macbeth to find a talent rather than to kill the king and there would be no evil deaths or mischievous scenes that created mistrust and disloyalty. There would no longer be a theme of corruptness, but a theme of heroism and admiration. If the story took on this plot instead of the one it actually had, Lady Macbeth would have no role in the play because her only role was to encourage Macbeth to do whatever it took to get the power of the throne. I guess her role  could have been helping inspire him in building his talent and doing good things, but the story would be completely opposite if the story took on this plot. All of the character's actions would be the complete opposite. This would turn the story around in a 180 turn, but I think I would like that version better than this one.
