How was victor changed by the end of frankenstien

When he finished telling his story to Captain Walton at the end of the book he didn't chage at all. Becase if you notice he still wanted revenge and never said anything about it being his fault for the monster's rage. But then in his last minute, he said "I realize now that I am to blame for deserting my creature after I formed him." Thats what caused all the chaos in the first place, then he said "Now, I have a responsibility to all of mankind to see that this creature is stopped before he murders again." Now this shows that he no longer wants revenge but to stop it so there will be no more murders. And also he wanted to kill the creature himself, but then since he knew he was dying he asked Captain Walton to do it for him. He learned to let go of what he wanted done, and find a new way to do it.
