Victor Frankenstein has been fixated on creating human life from inanimate bodies parts and has worked himself into the ground to achieve this goal, isolating himself from other people. However, he has not sufficiently imagined or thought through what will face him on the other end and is not emotionally prepared for what he sees. When the creature comes to life, it is so hideous that Victor flees it in terror and revulsion.
Abandoned, the creature finds that he is rejected by humankind. When he finally encounters Victor in the Alps some two years later, the creature has taught himself to read and to speak. He communicates the anguish he has experienced at being abandoned and made a lonely outcast, and he demands that Victor build him a bride. Victor is moved by his words—and his threat to retaliate if he is not given a mate.
In the end, however, Victor is unable to fully empathize with the needs of his creature. He rips apart the bride, fearful of a race of such beings emerging if Victor and his bride can have children. He never offers the creature an alternative life, perhaps by making him a part, even if hidden, of his own family or offering him love and companionship with himself or in some other way. He simply abandons the creature a second time, leading his creation to destroy Victor's family and then chasing Victor with the intent of killing him.
For all his seeming refinement and sensitivity, Victor is never able to see through the monster's appearance to his suffering and inherently kind human soul underneath that yearns for love. This has been read as a parable about both childbirth—the revulsion a mother can experience at her newborn—and about colonialism, signalling the revulsion that Europeans sometimes felt at the appearance of native peoples in other parts of the world.
