I urgently need you to revise these sentences. In particular, I don't think sentence 2 is grammatically correct. Thank you.

1) In "Macbeth", as in many of his comedies and tragedies, Shakespeare offers a profound reflection on a theme which is both modern and universal: life is a play and the world is a stage.
2) The metaphor of the world as a stage was common in Renaissance culture, but in Shakespeare’s great works it becomes an essential part of the plot and the characters’ psychology.
3) In his last monologue Macbeth uses four metaphors to describe life: a walking shadow, a poor player, a brief candle and a tale told by an idiot.
4) Life is no more than a walking shadow – a poor actor – who goes through all the emotions in one hour on the stage and then is heard no more. 5) Life is like a brief candle which is going to extinguish, a tale told by an idiot signifying nothing. In other words, all achievements in life pose no barrier to the coming of death.
6) He has realized that man has the illusion of being able to change his destiny but each step he takes in that direction simply confirms and consolidates the future established by Fate.
