Methinks he has not read Scott Peck's "People of the Lie"
"The evil deny the suffering of their guilt - the painful awareness of their sin, inadequacy, and imperfection - by casting their pain onto others through projection and scapegoating. They themselves may not suffer, but those around them do. They cause suffering. The evil create for those under their dominion a miniature sick society"
Cheers,
And why the evil do this is also insructive.....to avoid pain themselves!
It's basic, craven fear with its comcomitant selfishness on display.
For those with "eyes to see", that is.
