If you look honestly at humanity, the motivations of the average person are selfish and unenlightened. An internet mod enjoys authority and an elevated sense of self worth by putting other people down.
There really are some people genuinely enthused by virtues such as intellectual discovery and shared dignity, but they're in short supply and likely to be outnumbered in the population clamoring to become internet mods.
I've had a few posts removed from a SO site after I corrected someone who happened to be a mod there. And the Innocence Project fights to give innocent people their lives back because some prosecutors don't want a scratch on their resume.
I think it would be better if we acknowledged these realities more-often rather than pretending all the evil people in the world died in Nazi Germany, or wherever, and they weren't just normal people.
I think this is also why I always retreat into nerdy or intellectual endeavors. Not because I am particularly intelligent, but because the real world is so ugly.
There is no real excuse here as far as human cognitive ability goes. The problem is with morality.
I think these examples show that as humanity goes forward I think moral integrity/intelligence/bravery is more important to develop than our purely technological and scientific capabilities.
