Then if thou hast
A heart of wreak in thee, that wilt revenge
Thine own particular wrongs and stop those maims
Of shame seen through thy country, speed
thee straight,
And make my misery serve thy turn: so use it
That my revengeful services may prove
As benefits to thee, for I will fight
Against my canker'd country with the spleen
Of all the under fiends.
