No doubt that Bezos is mentally ill, all the billionaries are becasue of usury's psychological consequences. The natives called such behavior Wetiko or Windigo, a soul devouring monster we know as a psycho-spiritual disease of self-devouring greed. If assasinated another will take his place, I don't believe your proposals go far enough. To change the behavior we have to change the most influencial system on behavior humans have divised, the money system, and change it to serve instead of to master. All the systems we depend on are ruled by the money masters.
