In recent years transformational leadership has been questioned by the ``Hitler problem'': is Hitler a transformational leader the same way as Gandhi or Mother Teresa? How can we distinguish leaders from manipulators?
Instead of looking at specific values that a ``good'' leader should exhibit, this paper proposes looking at the relationship that is created between the leader and the collaborator (partnership), which is the result of the values and behaviors of the leader. The partnership promoted by the leader demonstrates sets of values and behaviors in a more objective and
measurable form, and avoids entering the cultural relativism problem.
