Jekyll and Hyde

We now dissociate ourselves from our failure. We see mental health as something that unaccountably drops from the skies onto us and blame some of our wickedness on unconscious biasses which can be trained away as if they happened to a third person who has nothing to do with us. Is this not exactly the same thing as the Jekyll and Hyde syndrome where our evil is hived off into a blameable surrogate so that we can continue to flatter ourselves that we are free of all stain? An inability to deal with what we really are or the creation of a scapegoat within ourselves but not ourselves? Is this just a very Victorian problem resurrected?
