It were done quickly: if the assassination
Could trammel up the consequence, and catch,
With his surcease, success; that but this blow
Might be the be-all and the end-all here,
But here, upon this bank and shoal of time,
We’d jump the life to come. But, in these cases,
We still have judgment here; that we but teach
Bloody instructions, which, being taught, return
To plague the inventor: this even-handed justice
Commends the ingredients of our poisoned chalice
