MALCOLM: Be comforted.
Let’s make us med’cines of our great revenge,
To cure this deadly grief.

MACDUFF: He has no children. All my pretty ones?
Did you say “all”? O hell-kite! All?
What, all my pretty chickens and their dam
At one fell swoop?

MALCOLM: Dispute it like a man.

MACDUFF: I shall do so,
But I must also feel it as a man.

William Shakespeare (1564-1616) English dramatist and poet
