Frankenstein fails his creature in a number of different ways. First and foremost, he unleashes the monster upon a world that his creation doesn't really understand and in which he struggles to live. At no point has Frankenstein acted like a parent and prepared the Monster for life in the outside world. He hasn't given him any love, nurturing, or guidance; he's simply washed his hands of him and left him to figure things out by himself.

To some extent, the Monster's violent actions are a way for him to cope with a strange, harsh world in which he doesn't truly belong and for which Frankenstein hasn't prepared him. But the ultimate responsibility for his actions lies with his creator, who's failed not just the creature, but the world as a whole.

Frankenstein further fails the Monster by refusing to make him a companion. Horrified by his first creation, Victor is deeply reluctant to make another one. But the Monster, who lacks the maturity and understanding to see the bigger picture, sees Victor's refusal to provide him with a mate as a profound injustice. Thus, he makes a blood-curdling threat to Frankenstein and his bride that he will see them on their wedding night.

Victor fails the creature immediately upon its creation, and he continues to fail afterwards. Although created as a fully-grown adult, the creature is in essence an infant who must depend on a parent to nurture and teach it. However, Victor never takes on the role of parent, even though he is responsible for bringing this new life into the world. Instead, he rushes out of the room in horror at what he has done and fear at what he sees. His immediate response to the creature sets the tone for its interactions in life and for its views of itself and others. Seen as a hideous monster by his own father, he is doomed from the start of his life. Consequently, the creature seeks the comfort of others, only to be rejected time and again by society.

Victor consistently fails his creation, his child, not only by refusing to give him the love he crave,s but also by refusing to help him acclimate. Part of a father’s role is to teach a child to deal with and fit in with the world. The creature wishes to belong, yet he cannot, because he is visually frightening—because Victor made it that way. Although he’d had a plan when working on his creation, Victor had never thought ahead to what the end result would look like or its role in society. The creature cannot communicate with others (at first) because it has no education—because Victor ran away from his responsibility to teach him. He must learn on his own while hiding away from others, aware of the great fear and disgust that he causes. The creature needs companionship, but he cannot have a parent, a friend, or a mate because Victor refuses to be part of his life or to fashion a mate. The last insult for the creature is the denial of any type of happiness, since he will never have someone to share his life. Perhaps if Victor had gone through with his promise, the creature might have been satisfied.

Victor’s great fear results not only from seeing how horrifying the creature looks, but also from a much larger epiphany: he has attempted to play God in a most unnatural way. He has created this monster out of his own need to be recognized by the world, but his fear prevents him from taking any responsibility for the monster's growth. Ultimately, he does feel responsible to destroy that which he has created, but at great expense to others. Because Victor fails the creature, his loved ones suffer the consequences.

Victor fails his creation by recoiling from it in horror and being unable to love it once it comes to life. He realizes too late that in his pride, his desire to emulate the divine, he has made a mistake.

Yet his mistake lives. As a living creature, a species of a human, the monster craves the love of his creator and the love of other human beings. Nevertheless, the horrified Victor abandons his creation. 

Victor compounds that first wrong by agreeing to make a female companion for his monster, and then destroying that female creation, fearing it will be more evil than the first monster and that a race of monsters will be born. At this point, betrayed and abandoned, the monster vows revenge, wanting to hurt his creator the way he has been hurt. 

Escaping to the solitude of the Arctic, the monster, discovered by Frankenstein, speaks to him in poignant terms.  It is difficult not to sympathize with his lonely plight:

Believe me, Frankenstein: I was benevolent; my soul glowed with love and humanity: but am I not alone, miserably alone? You, my creator, abhor me; what hope can I gather from your fellow-creatures, who owe me nothing? They spurn and hate me. The desert mountains and dreary glaciers are my refuge.

Much of Frankenstein criticism focuses on Victor Frankenstein and his abandonment of his creation, the Creature. Victor abandoned the Creature once he saw it. In volume one, chapter 5, Victor states, "Unable to endure the aspect of the being I created, I rushed out of the room." As the text continues, the Creature finds Victor, and mumbling, Victor runs away again. Victor's hostile and negative reaction toward the Creature was simply because the Creature did not look like or turn out as Victor had imagined. This abandonment of the Creature can be compared to a parent giving birth to a child, then abandoning it, which is essentially what Victor did. Why did Victor do it? Was it ego? fear? Most likely both and more. Victor's desire for power and control overtook him, and as the story continues, one could argue that the Creature's demise was because Victor had abandoned him at his most vulnerable time.
