Leaders that traffic in fear are imposters. They attempt to use fear to control those they presumably lead. Such positioning is designed to broaden the leader-follower power differential. Leaders who traffic in fear do so to increase (artificially) their leverage and control over followers.
The best leaders I know embolden us and enable us. They insist that, together, we can overcome extraordinary challenges. They invite us to be our best and strongest selves, rather than our weakest and most dependent selves.
Fear-based leadership is all about enhancing the status of the leader.
Leadership that encourages us to be bold and exercise our best gifts to overcome obstacles is all about empowerment.
There's plenty of examples of both to observe and learn from.
