Leaders who do the right thing are applying which of liden's servant leader behaviors?

The answer is: Behaving ethically

Leaders who are behaving ethically will had a set of principles that they swore to follow in order to bring properties to the people that they led without compromising other people outside their group.

This type of leaders usually rise up to the top of the hierarchy due to admiration from the people rather than using fear and intimidation.

if interdependence implies a two-way dependence, and if each partner is equally dependent on the other for success, then there is an equal commitment to the making the partnership successful. the advantage is sustainability of the relationship, the disadvantage is that decisions are "democratic" and therefore may take longer to reach and more likely to be a compromise (which is not always the best solution). as the interdependence moves away from equality, the decisions become more influenced by the more independent partner. in the extreme the relationship becomes more dictatorial and more like "master-slave". generally the relationship has less commitment in both directions and is more likely to be temporary.

if one generalizes (and one shouldn't), equity partnerships, which is probably what is implied by interdependence, can be slow to progress or change but durable. the extreme alternative, independent-dependent partnerships tend to be efficient but more fragile.

hope this but you will have to site your own evidence. : )
