In Macbeth, what was life in Scotland like under Macbeth's reign?

There is no doubt as to Malcolm's and Macduff's revulsion
for the usurper of Scotland. At the very outset of the scene, Macduff enthuses Malcolm
to take up arms and defend his inheritance and birthright. Macduff is outraged to see 
dead bodies of young men: widows and orphaned children bereft and grieving the loss of
loved ones. Their screams of agony rending the air and reverberating to the heavens
themselves.

Initially, we sense caution in Malcolm as to
his relationship with Macduff. He is suspicious of Macduff because he openly tells
Macduff that he has been a close friend of the tyrant and a favourite. His assumption is
that Macduff might have arrived in England only to lure the "poor, innocent lamb" into
the traitor's snare. He's of the opinion that Macduff may stand to gain by betraying
him. He quotes the example of Lucifer, who'd been God's favourite angel and yet was
thrown down from heaven because of his rebellious nature. He hints that Macduff too
could fall from grace and turn traitor.

There is no doubt
that Malcolm feels uneasy in casting aspersion on Macduff, but, that is only to protect
himself from being ensnared. He tells Macduff that he must not think of his suspicion as
dishonour to himself, for he may be quite honourable despite what he thinks of
him.

Macduff is appalled and visualizes the end of
Scotland, since its heir and successor, has lost faith even in those men who are loyal
to him. He grieves and says that Scotland will continue to bleed and there will be no
retribution for the evil and the wicked because "goodness dare not check
thee".

Malcolm is aware that Scotland is doomed and each
new day sees a fresh wound inflicted upon it. He knows that the tyranny and oppression
that Macbeth has unleashed upon its hapless people will not cease unless a greater power
is set forth toward Scotland to cower the brute and bring him to his
knees.
