How it did grieve Macbeth! did he not straight
In pious rage the two delinquents tear,
That were the slaves of drink and thralls of sleep?
Was not that nobly done? Ay, and wisely too;
For 'twould have anger'd any heart alive
To hear the men deny't. So that, I say,
He has borne all things well: and I do think
That had he Duncan's sons under his key—
As, an't please heaven, he shall not—they should find
What 'twere to kill a father; so should Fleance.
