Yep, that though experiment is specifically designed to show that idea of objective external source of morality is absurd. Internal source like you described is also objective, it is shared among all humans and based on objective realities of evolution and history. I bet psychopaths share significant portion of it with neurotypical humans as well -- they just have different weights among multiple contradicting heuristics and/or certain mechanisms working slightly differently.
