I guess we need a charitable interpretation of "People are crazy, the world is mad"-- people are very much crazier than they theoretically could be (insert discussion of free will).

I believe that people do very much more good (defined as life support for people) than harm, based on an argument from principles. If people didn't pour more negentropy into the human race than they take out, entropy would guarantee that the human race would cease to exist. The good that people do for themselves is included in the calculation.
