Are we that ahead?

Heard this from a documentary about the Vietnam War:

We think that we are civilized and ahead of all the other wild animals we clothe ourselves and educate one another. But we are also the only species that never tire of killing one another and hatred towards each other.

I am not sure how what was really said because I only heard it once and did not pay much attention to it until the end of the sentence.

Got me thinking.
