He thinks he'll be remembered as the villain in the story. But I forgot to tell him that the villain is usually the person who locks up the maiden and throws away the key. He was the one who let me out.

La gente no sólo es propensa a olvidar los favores y las injurias, sino que acaban por odiar a quien la favoreció y por olvidar el rencor que sentía por el que la ofendió. El empeño en recompensar el bien y vengarse del mal le parece una servidumbre demasiado onerosa

In the fairy tale you mentioned last night, I would probably be the villain. But it's possible the villain would treat you far better than the prince would have.

I cannot forgive myself for what I did. It has long been one of my strictest principles not to interfere with the life of any individual, let alone attempt to shorten it. If an exception were to be made, Dr. Helvitius would surely qualify. It might be argued that, having neither scruples nor conscience, he had no claim upon the conscience of someone else — least of all, his intended victims. But that is a question to be resolved by a judgment higher than mine. In the event, my responsibility toward Vesper outweighed every other consideration.
I can state in all honesty: I meant only to wound him.
I cannot forgive myself — for missing the villain completely.

Nor have I forgotten sir. that the charity of his daughter delivered me from his power. I can forget injuries but never benefits.

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?
