what is surprising about what the creature says when he visits victor?

Surprisingly, the creature asks for forgiveness..... for Victor's pardon.

“That is also my victim!” he exclaimed. “In his murder my crimes are consummated; the miserable series of my being is wound to its close! Oh, Frankenstein! Generous and self-devoted being! What does it avail that I now ask thee to pardon me? I, who irretrievably destroyed thee by destroying all thou lovedst. Alas! He is cold, he cannot answer me.”
