What is the worst flaw of humanity? Is it an inherent weakness or selfishness? Is it the tendency towards violence and hate? Or what? Or is the fact that humans are flawed a good thing? Is perfection a thing to be admired for its essence or despised for its emptiness? What say you?
And what do I think? I believe the root of all problems stems from either idiocy or weakness, depending on the situation. So those would be the two biggest flaws in my eyes.
