There is a simple explanation for our "morals". Common sense.

If we all fought each other for no reason we would be extinct, and our technological progress not regarding war would be at a standstill.

Also, here is an example of evolution removing stuff like agressiveness from livestock.

1. A farmer buys cattle from the market.

2. He finds that some of them are very agressive or are intelligent.

3. He slaughters the agressive and intelligent sheep first to prevent those traits from being passed on.

4. The next generation of cattle are docile and less intelligent than their predecessors, and so are much easier to handle by the farmer.
