Our dear 'Draco Malfoy', the complex villain from 'Harry Potter' series, shows remarkable character development throughout. After siding with the Dark Lord, he realizes the consequences of his choices. Post-war, he goes on to marry Astoria Greengrass and they have a son named Scorpius.
Living his everyday life is his redemption as he raises his son differently, implying he regrets his past, and in the end he's seen exchanging polite nods with Harry. After all, he is the epitome of 'everyone has a chance at redemption'.
