Psychopaths lack the ability to connect and understand others emotional states is the main reason they are so damaging. That natural feeling you get when someone is super happy or super sad without needing to look or observe them is what Psychos lack. In theory it really is a sad state of being. This in turn causes them to never truly connect to others deeply enough and to create meaningful relationships. Narcissistic Psychopaths are the much more dangerous. Believing they are above everything else stacked with no amount of emotional connection is a combo made in hell. All of this allows them to climb over others to get to the top. No doubt a lot of higher ups have a great detachment from humanity to be able to hurt others for personal gain.
