And mentally ill people can do this very thing and cause the same effect to the victim without even knowing it because they really believe it. Doesn't change the result at all a spouse can drive one mad. Been there.
To me, that seems different, fundamentally because mentally ill people may indeed think they are telling the truth.
It takes a special kind of a-hole to do this deliberately to cause anguish and pain, and Leftists from top to bottom do this as a matter of course.
