And this is one of the rare times I think he’s being truthful - he can’t understand anyone wishing to have a loved one with them instead of money. He just can’t grasp it so he makes that joke.

narcissism is a spectrum. this dude is way into the infrared. Even Roy Cohn was shocked by his callousness in the end (not that he didn't richly deserve it).

He also literally couldn't understand why anyone would sacrifice themself for the greater good (in war, but I'm sure in literally any circumstance). He would 100% do the "Dead Zone" move of holding a baby up to shield himself from an assassin if that were available to him. His own grandchild, even.
