SOLILOQUY:

She should have died hereafter;
There would have been a time for such a word.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing

At this soliloquy Shakespeare is in some way saying that Macbeth is just a puppet that he is the one that controls the situation, and that the others characters are puppets as well and that life is short if you do bad things that you will be alone when he says “She should have died hereafter ” is like saying in other words that she was going to day at anytime. also when he says “Creeps in this petty pace from day to day to the last syllable of recorded time” he means that that all the days are not  just peaceful that people die because they have to,  and that the ones that are still alive have to remember the last words that come out from the character that has just died, like when he says “And all our yesterdays have lighted fools, the way to dusty death. Out, out, brief candle” is saying that macbeth is pass he act like a stupid psychopath, dirty kills meaning that it wasn’t official battle that he kill the people when they weren’t looking and that is the most disgraceful a men could do when saying Out,out & out brief candle saying that life is short that if you waste your time doing bad things people are going to end up being alone with no friends because you make then get burn like a candle burns inside and shows the reactiong outside. When he says that “Life’s but a walking shadow” he is saying that the shadows are alone there are just shadows when saying walking he means that macbeth is one. A human being alone is mostly like a shadow. When saying a poor player he is saying poor player he says that he have next to him no one that he is alone. continue:
