how do you know he does not exists?
He does not exist simply because he will always be someone's pawn. He will be manipulated.
Your reasoning is a weak leader will be manipulated and thereby lose all his goodness and righteousness?
The key word is lead. To strike out in a direction. At best the person will be conflicted. I know many conflicted people who want to be good but do bad things. In that sense they are different from perfect predators who have lost their conscience. But the effect of the actions of both are similar except one feels pain for a period.
It is very hard to follow you because you cannot write in a lucid way that ordinary blog readers can comprehend :)
