While I don't think god designed anything I think evolutionary processes do feedback a natural morality and justice when resources are easily found. So in a place with plenty of food then behaviour that is less moral is generally less effective. This effect scales into importance the more complex the social group. Humans are the most complex but you can still see animal societies where protection of kin ( the selfish gene) is moral and more effective than every man for themselves strategies which tend to predominate in resource scare environments.
In human society, just as 1 in every 10 smokers may well be able to smoke without suffering severe health problems, it is possible for in individual to escape social or physical consequences of immoral choices but overall there is a feedback, drink drivers suffer more injuries and deaths, thieves tend to have lower quality economic lives, gregarious people live longer, family orientated people tend to be happier on most measures and so on. Remember though that morality is relative. It is entirely moral , from an evolutionary standpoint, that in times of resource scarcity or immediate danger to act differently. During war, famine , personal attack we quickly discover that pious meekness and turn the other cheek are fairly useless traits in self or group preservation.
