Can a superhero be redeemed after becoming a villain?

The only verified information concerns the 2024 film Madame Web, which follows Cassie Webb’s origin story as she confronts her past and protects three young women from a villainous antagonist. The film’s plot does not describe a superhero character turning into a villain, nor does it detail any redemption arc for such a transformation. Because the evidence does not mention a superhero becoming a villain or a subsequent redemption, there is no basis to assert that a superhero can be redeemed after becoming a villain.
