Please help. You don't necessarily have to give me the answer but at least help me understand HOW to get the answer. It would be much appreciated. Thanks! Using these lines from Act II, explain the relationship between Macbeth's words and the words of Duncan's sons.

Macbeth

Had I but died an hour before this chance,
I had liv'd a blessed time; for, from this instant

All is but toys: renown and grace is dead;
The wine of life is drawn, and the mere lees
Is left this vault to brag of.

Malcolm

To show an unfelt sorrow is an office
Which the false man does easy. I'll to England.

Donalbain.

To Ireland, I; our separated fortune
Shall keep us both the safer: where we are,
There's daggers in men's smiles: the near in blood,
The nearer bloody.
