What less than doomsday is the Prince’s doom?

Romeo
What less than doomsday is the Prince’s doom?
Friar Lawrence
A gentler judgment vanished from his lips:
Not body’s death, but body’s banishment.
Romeo
Ha, banishment? Be merciful, say “death,”
For exile hath more terror in his look,
Much more than death. Do not say “banishment.”
Friar Lawrence
Friar Lawrence
Here from Verona art thou banishèd.
Be patient, for the world is broad and wide.
Romeo
There is no world without Verona walls
But purgatory, torture, hell itself.
Hence “banishèd” is “banished from the world,”
And world’s exile is death. Then “banishèd”
Is death mistermed. Calling death “banishèd,”
Thou cutt’st my head off with a golden ax
And smilest upon the stroke that murders me.
Friar Lawrence
O deadly sin, O rude unthankfulness!
Thy fault our law calls death, but the kind prince,
Taking thy part, hath rushed aside the law
And turned that black word “death” to “banishment.”
This is dear mercy, and thou seest it not.

Heaven is here
Where Juliet lives, and every cat and dog
And little mouse, every unworthy thing,
Live here in heaven and may look on her,
But Romeo may not

Romeo
’Tis torture and not mercy. Heaven is here
Where Juliet lives, and every cat and dog
And little mouse, every unworthy thing,
Live here in heaven and may look on her,
But Romeo may not. More validity,
More honorable state, more courtship lives
In carrion flies than Romeo. They may seize
On the white wonder of dear Juliet’s hand
And steal immortal blessing from her lips,
Who even in pure and vestal modesty
Still blush, as thinking their own kisses sin;
But Romeo may not; he is banishèd.
Flies may do this, but I from this must fly.
They are free men, but I am banishèd.
And sayest thou yet that exile is not death?
Hadst thou no poison mixed, no sharp-ground knife,
No sudden mean of death, though ne’er so mean,
But “banishèd” to kill me? “Banishèd”?
O friar, the damnèd use that word in hell.
Howling attends it. How hast thou the heart,
Being a divine, a ghostly confessor,
A sin absolver, and my friend professed,
To mangle me with that word “banishèd”?
Friar Lawrence
Thou fond mad man, hear me a little speak.
Romeo
O, thou wilt speak again of banishment.
Friar Lawrence
I’ll give thee armor to keep off that word,
Adversity’s sweet milk, philosophy,
To comfort thee, though thou art banishèd.
Romeo
Yet “banishèd”? Hang up philosophy.
Unless philosophy can make a Juliet,
Displant a town, reverse a prince’s doom,
It helps not, it prevails not. Talk no more.
Friar Lawrence
O, then I see that madmen have no ears.
Romeo
How should they when that wise men have no eyes?
