In Chapter 10, why does Victor decide to accompany the figure?

I think Victor realizes the figure is the creature. As if summoned by this call, the monster appears. Victor rains curses upon him and threatens to kill him, but the creature remains unmoved. He says that he is the most wretched and despised of all living things, and accuses his creator of a gross disregard for the sanctity of life: how else could Victor propose to murder a creature which owes its existence to him? The monster asks Frankenstein to alleviate his misery, and threatens to "glut the maw of death... with the blood of [Victor's] remaining friends" if he does not comply with his wishes.
