"I am determined to prove a villain"(1.1.1).
If heaven have any grievous plague in store
Exceeding those that I can wish upon thee,
O, let them keep it till thy sins be ripe, (1.3.11)
I do the wrong, and first begin to brawl.
The secret mischiefs that I set abroach
I lay unto the grievous charge of others.
Clarence, whom I, indeed, have laid in darkness,
I do beweep to many simple gulls
Namely, to Hastings, Derby, Buckingham;
And say it is the queen and her allies
That stir the king against the duke my brother.
Now, they believe it; and withal whet me
To be revenged on Rivers, Vaughan, Grey:
But then I sigh; and, with a piece of scripture,
Tell them that God bids us do good for evil:
And thus I clothe my naked villany
With old odd ends stolen out of holy writ;
And seem a saint, when most I play the devil. (1.3.28)
