"How all this will terminate, I know not; but I had rather die than return shamefully,--my purpose unfulfilled" -page 160

This was said, well, written by Walton in a letter to his sister. It seems that Walton's sense of determination is very similar to that of Victor's. Walton wanted to reach the arctic circle so badly that he was reluctant to turn back even in the most intense of conditions. Victor wouldn't rest until he sought his revenge on the monster. This is also very similar to when he created the monster. While he was in the process of creating him he neglected everything including his own health. I think that the parallels drawn between the two help point out the more important themes present in the novel.
