Loving God and my neighbor as myself.
There are many avenues of evolution. Individual selection, sex selection, group selection. The ability to cooperate is fully acknowledged by scientists as a major factor in group selection. Cooperative groups out compete non-cooperative groups every time.Darwin certainly believed it was. Species compete for food, water, and room. Individuals compete for mates and everything else. All individuals must claw or eat all others to survive and prosper in a deadly game of "survival of the fittest".
As you suggested life isn't like this. Life is cooperation to maximize life. When something doesn't work it ceases to exist either by changing or extinction.
