It is an odd predicament.
Many times in a group of people there is often a leader who rises from within due to their trustworthiness, performance, dependability, selflessness, and so on and so forth. BUT having such a leader AND giving them such power can leave the group as a whole weaker should that leader perish.
There are moments when consent within a group is terribly difficult to achieve and ofter you need that "leadership" individual to make a decision that everyone goes along with BECAUSE of the trust that leader has earned.
Without that person the group may never agree on anything and become stagnant at best, dissolve at worst.
