Without any flaws, what would y'all walk on?
Okay, cheap joke.
What are flaws? I can name a few - hatred, bigotry/favoritism, discord, jealousy, rage, hypocrisy, laziness, selfish ambition, trollishness, envy, drunkenness and addiction. I guess the common factor is an over-reaching sense of entitlement, especially when it is expressed to the detriment of society.
