The term competence seems to be throwing people off, which I can understand but I think the point here is very insightful. It's important to separate those with a hero complex from those that are more morally sincere. Greater moral sincerity means you're more concerned with solving the problem than being the one to solve the problem. It's not about you, it's about the problem and seeing it solved. I think this is an especially relevant point in today's culture.
