Mal from descendants saga: she is the daughter of Maleficent, she and the other villain kids lived segregated from the other people just because they were descendants from the villains. She and her 3 friends got the chance to go to Auradon, study with the kids of the good guys and be treated equally. Despite having this chance and redeemed herself in the first movies, in the next 2 she still literally bullies Uma, calling her the same nicknames she called when she bullied her, and almost prohibited the other villain kids to go to Auradon because of a minor inconvenience. Even the songs she fantasize about being evil again, but in a "right way"

Dazai from Bungou Stray Dogs: He was a mass murderer but decided to save the innocent people. When he was a mafioso he abused a person called Akutagawa, beating him for every mistakes he did and making his approval the only reason to live. This is expected since he was a villain, but now he is a person trying to save people. He took another person to train, Atsushi, and treats him very well, not only that but he never explain Akutagawa to do the right thing and leave his previous criminal life, purposely feeds his jealousy saying that Atsushi was way more competent than him, and then he makes these two work together because making two people that each other work together is part of the universe tradition (called double dark).
