In Frankenstein, “what are the two ways in which the narrator changes over the course of the story?

"You are in the wrong," replied the fiend "and instead of threatening, I am content to reason with you. I am malicious because I am miserable. Am I not shunned and hated by all mankind? You, my creator, would tear me to pieces and triumph; remember that, and tell me why I should pity man more than he pities me? This passion is
detrimental to me for you do not reflect that YOU are the cause of its excess. If any being felt emotions of benevolence towards me, I should return them a hundred and a hundredfold; for that one creature's sake I would make peace with the whole kind! What I ask of you is reasonable and
moderate; I demand a creature of another sex, but as hideous as myself; the gratification is small but it is all that I can receive and it shall content me. It is true we shall be monsters cut off from all the world but on that account we shall be more attached to one another. Oh! My creator, make me happy; let me feel gratitude towards you for one benefit!"
I was moved and shuddered when I thought of the possible consequences of my consent but I felt that there was some justice in his argument as his tale and the feelings he now expressed proved him to be a creature of fine sensations and did I not as his maker owe him all the portion of happiness that it was in my power to bestow? He saw my change of feeling and continued,
"I swear to you by the earth which I inhabit and by you that made me, that with the companion you bestow I will quit the neighborhood of man and dwell, as it may chance, in the most savage of places. My evil passions will have fled, for I shall meet with sympathy! My life will flow quietly away and in my dying moments I shall not curse my maker."
His words had a strange effect upon me as I compassionated with him and sometimes felt a wish to console him but when I looked upon him I saw the filthy mass that moved and talked, my heart sickened and my feelings were altered to those of horror and hatred. I tried to stifle these sensations. I paused some time to reflect on all
he had related and the various arguments which he had employed and thought of the promise of virtues which he had displayed on the opening of his existence and the subsequent blight of all kindly feeling by the loathing and scorn which his protectors had manifested towards him. After a long pause of reflection I concluded that the
justice due both to him and my fellow creatures demanded of me that I should comply with his request. Turning to him, therefore, I said,
"I consent to your demand, on your solemn oath to quit Europe forever, and every other place in the neighborhood of man, as soon as I shall deliver into your hands a female who will accompany you in your exile."

A - He is moved by the fiend’s words and develops compassion for him.

B - His feelings of hatred and horror are deepened for the fiend he created.

C - He regrets accepting the fiend’s demand and feels guilty about his actions.

D - He relents to the fiend’s demand and consents to create a female counterpart.

E - He disagrees with the fiend and refuses to accept his demand for a female companion.
