Humanity is capable of wonderful things and horrible things, usually both at once. A cursory glance at history reveals a readily visible long precession of cruelty and thoughtlessness, but it also shows cooperation, beauty, altruism, and resistance to cruelty. Insisting that we should never look at the good things because the bad things exist does not make the world a better place. It's good that we're going back to the moon. We're going to learn a lot. Some of those things will help us, others will hurt us, but there's something to be said for our species using some portion of its effort to help us better understand our world. Maybe things like going to the moon can create opportunities to stop doing things like murdering each other en masse.
