Are We Evil?

I was catching up on Bolos' favorite NPR podcast, Radiolab, when I listened to one called, new normal.  they talked about whether or not Americans believe we will always be at war.

Apparently, in the 80's, one in three said that "yes, we will always be at war."  Now, though, they got about one in ten people who said "no, humans will never stop going to war."

The first story was about the male dominated society of baboons.  Basically, in one of group of baboons, due to to extenuating circumstances all of the alpha males die.  After they die, the women become outgoing towards new men trying to join the group of men.  Basically this violent culture is transformed into a peaceful utopia where everyone loves each other and the hierarchy essentially dissipates.

If the baboons' idea of war changed, then humans can change their beliefs about wars. I guess I wonder if we could learn to love (without killing all those who are violent).
