The question is "Have we evolved to the point that "win at all costs" trumps "truth and justice"? The term "evolve" seems to suggest improvement. That is,the term seems to suggest that something that was once lesser has became greater. "Win at all costs" seems to depict the worst of society; while "truth and justice" seems to suggest the best of society.
Darwinists would say that survival of the fittest has been the way of nature and natural selection, but that society is steadily improving in all aspects of life. From their point of view, human beings may be prone towards selfish ambition, but gradually over time humankind is growing closer towards a more cooperative state.
Christians in one sense agree that human beings are prone towards selfish ambition, but that under the auspices of God that ambition can be corralled for the good of society. Christians also believe that over time human's will choose more and more to ignore God and his will with the results that society will become worse rather than better.
So, simply put, Darwinists believe humankind is steadily (even if imperceptively) getting better, instituting its own utopia over eons of time; while Christians believe that society in more cases than not are rejecting God and getting worse over time. This is especially what we see in the United States which was largely founded on Christian principles. But never, since the US began have those principles been universely upheld and citizens (both Christians and non-Christians) still act in selfish ways. Moreover, we see relative morality or situational ethics becoming more of the norm which of course waters down or eliminates the propensity of truth and justice.
Either way, evolution gives the sense that society is getting better and that humans can and will negotiate a better tomorrow. Thus, a society shunning truth and justice for win at all costs would be the opposite or de-evolution, denigration, or moral erosion.
