When people get Akumatized or Re-Akumatized into something different they think they're working for who they're think they are. Hawk Moth has been evilizing many Parisians, offering each one something they want in return for the Miraculous. If I came to Paris and told an Akumatized villain, this: "You're not working for who you are." Would those poor Parisians care if they knew Hawk Moth was out to destroy the Earth & revive his wife? We want peace when Hawk Moth is defeated.
