Again, I'm not arguing for some naive Panglossian view. Things can get pretty bad transiently.
I just take exception at the cynical view that evil is somehow intrinsically more powerful than good.
"Survival of the fittest" is often misunderstood that way too, as survival of the strong and selfish, when, on the contrary, evolution is full of examples of cooperation being stable over long timescales.
I very much want to push back against any bias towards a just world. Bad people often live their whole lives without any consequence (think prostate cancer) while good people struggle (think my cuticles, which deserve much more than I usually give).
But if you look at long timescales, it's pretty obvious that cooperation is the more powerful strategy.
We used to live in tribes of hunter gatherers, in constant danger from a hostile environment. Now, we're part of a global technological superorganism that provides for us.
If free-loading was a dominant strategy, this would never have developed.
(1) From the evolutionary biology point of view this can be explained by rate dependent selection- meaning the strategy is strong as long as only a small fraction of a population employ it. Durkheim would probably say you need these people to establish what the norms of a society are.
