Childe isn't portrayed as part of the kind groups of heroes. Unlike the living women of the harbingers who get along with everyone and don't hurt anyone innocent, Childe is still shown to be a villain. You don't fear Sandrone or Arle doing anything to hurt others, but no one can say the same for Childe. Childe isn't shown as cute, he's clowned on and a joke but it's because the game is punishing him for being evil.
