What are Dr. Frankenstein's feelings when he returns home in Chapter 17?

Victor is torn. He thinks of the creature's supernatural strength, and about the great destruction he still might cause. He therefore determines to comply with the creature's request, in order to save both his family and the rest of humanity. The creature says that he will anxiously observe his progress and then leaves him. Victor descends the mountain with a heavy heart, and returns to Geneva haggard. At home he takes weeks agonizing over his decision to create another creature.
