We all are men, in our own natures frail, and capable of our flesh; few are angels. - William Shakespeare

What do I fear? Myself? There’s none else by.
Richard loves Richard; that is, I and I.
Is there a murderer here? No. Yes, I am.
Then fly! What, from myself? Great reason why:
Lest I revenge. What, myself upon myself?
Alack, I love myself. Wherefore? For any good
That I myself have done unto myself?
O, no! Alas, I rather hate myself
For hateful deeds committed by myself.
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?

O, full of scorpions is my mind!

I am very proud, revengeful, ambitious, with more offences at my beck than I have thoughts to put them in, imagination to give them shape, or time to act them in. What should such fellows as I do crawling between earth and heaven? We are arrant knaves, all. Believe none of us.
