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.
I think the word your looking for is compassion or empathy.
And yes studies have shown an inverse corelate between them.
