Stories with a happy ending are a contradiction and a risk of distortion and deception, because any happy ending cannot restore or replace the evil that has happened; instead, it contains the risk of causing forgetfulness. The happy ending introduces covertly the idea that a meaning can justify the evil that has happened.
This does not mean that we should not do research about the meaning of life, existence, the world, things of any kind. We just need to do this research in a critical way, trying not to forget the multiplicity of perspectives and meanings, the becoming of everything and the metaphysical objectivity of evil in our human, subjective existence and perspective.
