Basically overthrowing a government.
As we do not know which point in the novel you are at, it is impossible for us to determine what will happen in the portions of the novel that you have not read. However, we can try to make some general assumptions of what you might be thinking about the text.
In the novel Frankenstein, we quickly learn that Dr. Frankenstein is obsessed with achieving glory through science. He wants to create life, and is arrogant about his ability to do so. As this is a horror book, and as it is set during the Romantic period, we can assume that this obsession with science will become problematic and lead to tragedy.
Moreover, once the monster is created, we can see that it very quickly has an affinity towards humans. He wants to learn from them, and he is even able to learn language. Based on this, we can most likely conclude that the creature will be unhappy, as he will never be accepted by the people that he so admires and loves.
