This is a good question. As you know, Victor Frankenstein is mortified by his creation. He detests what he has done and wants to destroy it. That the “monster” would have a different view is not only understandable but also expected. As for how his account would be different, let me offer a few points.
First, the creature would say that he did not ask to be created. There is a responsibility of the maker to the creature. The creature actually quotes from John Milton’s Paradise Lost:
Did I request thee, Maker, from my clay
To mould me Man, did I solicit thee
From darkness to promote me?
These words would certainly echo in the creature’s heart. He would also expect that Victor would give him a mate and show compassion. We can be very creative in describing the creature's feelings here.
Second, the creature would possess a certain amount of humility and realism. He knows that he is not like others; he knows that his appearance is repulsive. He often, at first, tried to do good things for others to show his goodwill. His kindness goes far, but it is met with resistance.
Third, as the “monster” faces more and more rejection, he would undoubtedly grow bitter, and he will see that he is not entirely responsible for his crimes. Humanity has pushed him toward his violence by rejecting him and not showing any kindness or compassion. Here is a quote that shows this point—we can be poetic here and add a lot of creative details:
I, the miserable and the abandoned, am an abortion, to be spurned at, and kicked, and trampled on.
