And 'twere the cheaper way;
Better it were a brother died at once,
Than that a sister, by redeeming him,
Should die forever.

ANGELO.

Were you not then cruel as the sentence,
That you have slander'd so!

ISABELLA.

Ignominy in ransom, and free pardon,
Are of two houses: lawful mercy is
Nothing akin to foul redemption.

ANGELO.

You seem'd of late to make the law a tyrant;
And rather proved the sliding of your brother
A merriment than a vice.

ISABELLA.

O pardon me, my lord; it oft falls out,
To have what we'd have, we speak not what we mean:
I something do excuse the thing I hate,
For his advantage that I dearly love.

Towards the conclusion of the play we have another instance of that rigid sense of justice, which is a prominent part of Isabella's character, and almost silences her earnest intercession for her brother, when his fault is placed between her plea and her conscience. The Duke condemns the villain Angelo to death, and his wife Mariana entreats Isabella to plead for him.
