Considering the way there are people completely out of touch with reality (Elon Musk, Mark Zuckerberg, Jeff Bezos come to mind, among many others), is it possible that maybe all that greediness made them lose their humanity? Probably not literally but I guess moreso in a metaphorical way.
Actual psychopaths have brains that are wired differently than normal people, they are literally not capable of feeling empathy or are able to feel the pain they caused that allowed them to amass their fortune. So yeah in a way I think that makes them less than human.
