Quantum Denial Agent
One whom disowns friends and family at the slightest suspicion that people don't admire them as much they perceive themselves to be. The motivation for this individual is to maintain an ongoing effort to avoid some aspect of themselves that they have been unable to confront their whole life. This person is covered in a glossy anti-spiritual covering that is the equivalent of teflon and usually ends up being institutionalized.
