In doppelganger narratives the double reliably replaces the original who fades away

Evidence

In the books and films about doppelgangers that had come to fill my evenings, I was struck by how reliably this phenomenon occurred: eventually, the double replaces the original, through sheer energy and tenacity, while the original fades away or worse. Dostoyevsky’s novel The Double ends with Golyadkin, the tormented protagonist, being taken away to an asylum, driven mad by his imposter’s duplicity. — Naomi Klein, Doppelganger, 132
