What final advice does Victor offer Walton? What does it show about Victors character?

Though Victor looks forward to the peace that death will bring him, he despises the idea of dying with his task is unfulfilled. He begs Walton to kill the creature if he shows himself to him ­ no matter how eloquent and persuasive he seems.

This shows that Victor can never let go of his vendetta, he will die in the agony of unfulfilled vengeance.

Victor, also in a rare moment of sanity, tells the young captain to avoid ambition; only a moment later, however, he reconsiders, and says that Walton may succeed where he himself failed. With that, he dies. This tells us that despite his obsession to kill the creature, he has learned something about unbridled ambition.
