I think it’s sub-conscious self-hatred projected onto others. They are fractured, damaged people, that, from an early age were told that their vulnerabilities were weaknesses. Their inability to accept themselves as they are causes them to wreak havoc on the world searching for enough tangible reasons (power, fame, money) so that they finally can. But it’s never enough, because no amount of outer wealth will fill the void of inner poverty.

tldr: these people hate themselves
