First, I am so happy to finally be a part of this. Took me a long time to get on here. Just wanted to emphasize the concept of useful which Adler also emphasized. It is basic to the "belonging" concept and can be applied to the "dark side" discussion. Often what is seen as "dark" becomes "un-dark" if it is turned towards useful ends (Pew). It is somewhat anlagous to Jung's concept of acceptance (?). For instance a personality that strives for control can be healthy if the control is for the service of all. Compare personality of the CEO with the common criminal. Often the difference is only the degree of social interest.
