Quotation by Shakespeare

I am a villain. Yet I lie, I am not.
Fool, of thyself speak well. Fool, do not flatter.
My conscience hath a thousand several tongues,
And every tongue brings in a several tale,
And every tale condemns me for a villain.
Perjury, perjury, in the highest degree,
Murder, stern murder, in the direst degree,
All several sins, all used in each degree,
Throng to the bar, crying all, "Guilty! Guilty!"
I shall despair. There is no creature loves me,
And if I die no soul will pity me.
And wherefore should they, since that I myself
Find in myself no pity to myself?
