O, when the last account 'twixt heaven and earth
Is to be made, then shall this hand and seal
Witness against us to damnation!
How oft the sight of means to do ill deeds
Make deeds ill done! Hadst not thou been by,
A fellow by the hand of nature mark'd,
Quoted and sign'd to do a deed of shame,
This murder had not come into my mind:
But taking note of thy abhorr'd aspect,
Finding thee fit for bloody villany,
Apt, liable to be employ'd in danger,
I faintly broke with thee of Arthur's death;
And thou, to be endeared to a king,
Made it no conscience to destroy a prince.
