First of all, I think that Victor's decision to run away from the creature goes against his action prior to animating the monster. Before the creature came to life Victor was adamantly trying to go against the course of nature and alter lives. Now when he brings the creature to life instead of welcoming his creation he decides to run away. Now the creature is disoriented and knows nothing about what is going on. He is frustrated with Victor because he was to only person he saw when he was animated. The creature goes and kills many of Victors family members or people close to him. Which is kind of hard to believe that the creature would know who was Victors family just like that. If Victor had stayed and given the creature a chance the story might have been very different, and more boring than it already is. If Victor had stayed the monster might have been taught what is right and wrong like a child. The monster was neutral when it was animated and when Victor left it was confused and angry and became evil. If Victor had stayed the monster would instead be good. Some of the problems Victor would have faced include things like teaching the monster whats right or wrong, teaching it to read, having to deal with people being frightened with the monster, basically making him acceptable to society. Overall the story would have been adversely different and potentially more boring to read at the same time.
