Perfect is no more than 1 mans perspective, your real question boils down to are you willing to give your life to mold your "ideal world" or are you willing to inslave everyone for your "ideal world" both of which... are terrible.
My ideal world may be unpleasant to another person mind as is vise versa, why should I impose my opinion of perfection on the world? What makes me superior in judgment? Nothing, I am not all seeing or all knowing, i can not account for everything there is in my judgment. So i can not make a call like that.
The world is beautiful without this kind of interference. People all have their own personalities their own traits, their own ways of life and thats the way it should be. I can not imagine living in a world were everyone would be bent to my will, I take no pleasure in slaves, i prefer pure company, Just who they are and who they choose to be not me telling them what to be. That would be like living in some kinda of play that never ends, you just setting up dolls to knock them down for your own amusement. Things are the way they are for a reason. So i would choose nothing.
