Perspectives are the main focus of my response. Have you ever had a day, where everything you planned goes exactly as such? Your reasoning is what makes some days seem different from the next. Uncertainty makes us consider the good/bad; curious minds live life to see what factors in to alter our course. Not knowing what's edible in a different land, how would you find substance? Would you find a way to communicate with the locals, or would you eat whatever palm puts to mouth?
First, I have no wish whatsoever to multiply, fill the Earth, and - on top of it all - "rule over it all like a king or queen".
With regard to the question in general, I think there has to be the assumption that I would be without brain damage or mental illness that would prevent me from knowing the difference between good and evil? Because, unless people have a certain type of brain damage/lack of development or else mental illness, I don't believe it's possible for mentally healthy/undamaged people to live and not know the difference between good and evil. So, I'd probably pick living a long time and bringing the inevitable knowledge of the difference between good and evil along through my life.
As far as knowing more versus not really knowing what I don't know goes, the world is full of people who don't know stuff, don't know what they don't know, and are happy.
So my choice is to live a long time with whatever knowledge I have or don't have or will pick up along the way, without ruling anybody and CERTAINLY without doing too much multiplying. I'm not a giant egotist nor control freak. I hate the word, "rule" (within the context it's being used).
