Which do you think is the most powerful leader? .
Or the leader that threatens his people, and carries a big gun.
Personally I think it is easier to reject this kind of leader. It is easy to recognize that threats of violence and death are wrong. People will choose to follow or die as martyrs or for their cause to reject the leader. It's always easier to recognize the threat - it's upfront and you KNOW the danger.
The leader that can convince his people to follow his example, and trust him
This one is far more dangerous. Because of its subtlety it is much harder to identify. Therefore people can convince others to do things they would never do on their own because they are convinced their leader has their best interests at heart.
