Does it not, think'st thee, stand me now upon--
He that hath kill'd my king and whored my mother,
Popp'd in between the election and my hopes,
Thrown out his angle for my proper life,
And with such cozenage--is't not perfect conscience,
To quit him with this arm? and is't not to be damn'd,
To let this canker of our nature come
In further evil?
