The egotism of Victor is also apparent in this chapter as the reader can count the number of times that Victor uses I did this, I wanted that, etc. As he relates his reactions to his creation, he says,
The different accidents of life are not so changeable as the feeling of human nature. I had worked hard for nearly two years....For this I had deprived myself of rest and health. I had desired it with an ardour that far exceeded moderation, but now that I had finished...Unable to endure the aspect of the being I had created, I rushed out of the room....the tumult I had before endured....
That he is centered upon his own feelings is apparent in this passage as well as in the rest of the chapter, for Victor gives no indication that he is concerned about what has happened to his creation that he has fled.
I would say this this is the critical moment in the work when we begin to see Victor's lack of responsibility come to light. The common question that arises from the book is which character bears more responsibility for what happens: Victor or the monster. I have always felt that Victor has to retain more of the guilt because of his role of creation and his abandonment in the face of the "hideous progeny." Chapter 5 would go far in proving such an idea. I think that being able to gain insight into the parent who abandons child is probably one of the most relevant points of the chapter.
Chapter 5, in which Victor brings the Monster to life, demonstrates Victor's fickleness and unwillingness to accept responsibility for his actions. He spends months creating the creature only to despise it when it comes to life--because of his appearance! When he realizes what he has done, he faints and then flees from his creation, setting in motion all the horrific events to follow.
